Vill du installera och konfigurera W3 Total Cache på din WordPress website?
W3 Total Cache är ett populärt plugin för caching i WordPress som hjälper you att förbättra hastigheten och prestandan på din website. Tillägg för caching kan hjälpa till att behålla användare och sänka avvisningsfrekvensen, vilket kan hjälpa sökmotorsoptimering och öka konverteringen.
I denna guide för nybörjare visar vi dig hur du enkelt installerar och konfigurerar W3 Total Cache på din WordPress website.
Editor’s Note: Vi använder inte W3 Total Cache på vår website längre och har bytt till WP Rocket som är ett premium plugin för caching. W3 Total Cache är fortfarande en bra lösning som fungerar bra.
Vad är W3 Total Cache?
W3 Total Cache är ett av de bästa tilläggen för caching i WordPress som allow you att enkelt förbättra WordPress prestanda och hastighet.
Som standard använder WordPress PHP för att dynamiskt generera varje page på din website när den requestas av en användare.
PHP är ett programmeringsspråk på serversidan. Detta innebär att varje request från en användare ökar belastningen på din server. Detta påverkar din websites prestanda, användarupplevelse och sökmotorsoptimering.
WordPress tillägg för caching hjälper dig att minska detta genom att hoppa över PHP och servera en cachad kopia av din webbsida.
Det allow you också att enkelt ansluta din website till ett CDN (content delivery network) för att ytterligare förbättra din websites prestanda.
Installera W3 Total Cache i WordPress
Innan du installerar W3 Total Cache plugin i WordPress, måste du se till att du deactivate alla andra caching plugin på din website. Detta hjälper dig att save server resurser och förhindra eventuella plugin konflikter.
Därefter kan du gå vidare och installera och aktivera W3 Total Cache plugin. För mer detaljer, se vår Step-by-Step guide om hur du installerar ett WordPress plugin.
Vid aktivering kommer W3 Total Cache att lägga till ett nytt menu-item märkt Performance till din WordPress admin sidebar. Om du klickar på det kommer pluginets installationsguide att startas.
Klicka bara på knappen Nästa för att fortsätta.
Först kommer du att bli ombedd att aktivera Page Caching. Klicka på knappen Test Page Caching för att fortsätta.
W3 Total Caching kommer att visa dig olika alternativ för lagringsmotorer. Du måste välja den som sparar mest tid åt dig. Vanligtvis kommer det att vara alternativet ”Disk: Enhanced”-alternativet för de flesta plattformar för delade webbhotell.
Klicka på knappen Nästa för att fortsätta.
Nu kommer du att få alternativet att testa Database Cache. Vi rekommenderar att du väljer Ingen. För de flesta små till medelstora websites kommer din MySQL server att kunna hämta data snabbare än Database cache.
Klicka på knappen Nästa för att gå vidare till nästa steg.
Detta kommer att ta dig till Object Caching section. Object Caching allow W3 Total Cache att store database queries för dynamiska pages och återanvända dem för att förbättra prestanda.
Om testresultatet visar att det bara skiljer några millisekunder kan du välja None.
Klicka på knappen Nästa för att fortsätta.
Därefter klickar du på knappen Test Browser Cache och väljer sedan alternativet ”Aktiverad” under testresultaten.
Detta alternativ requestar användarens webbläsare att lagra en kopia av web browsern under en begränsad tid. Att hämta en page från webbläsarens cache går mycket snabbare än att hämta den från web serverns cache.
Klicka på knappen Nästa för att gå vidare till nästa steg.
Slutligen kommer Setup Wizard att be dig att aktivera lazy loading för images.
Nu kommer WordPress med built-in lazy loading för images. Vissa äldre webbläsare kanske dock inte har support för den utvalda funktionen.
W3 Total Cache använder JavaScript för att add to lazy loading för images, vilket kan vara ännu snabbare och mer effektivt.
Därefter klickar du på knappen Nästa för att slutför installationsguiden och view W3 Total Cache dashboard.
Avancerade alternativ för caching i W3 Total Cache
Grundinställningarna fungerar för de flesta websites. Det finns dock många avancerade alternativ som du kan konfigurera för att ytterligare förbättra prestandan.
Låt oss ta en titt på de viktigaste.
Minska JavaScript och CSS i W3 Total Cache
Termen ”minify” används för att beskriva en metod som gör filstorleken på din website mindre. Detta görs genom att vita utrymmen, rader och onödiga tecken tas bort från källkoden.
Note: Minifiering av JS och CSS-filer kan potentiellt förstöra din website. Om du aktiverar det och din website inte ser bra ut, inaktivera helt enkelt dessa alternativ.
W3 Total Caching allow you to easily minify JavaScript, CSS, and HTML source code as well. Vi rekommenderar dock att du endast minifierar JavaScript- och CSS-filer.
Bara heada över till Performance ” Minify page och rulla ner till JS section.
Kontrollera boxen bredvid ’JS minify settings’ för att aktivera den.
Nu rullar du ner till CSS section och aktiverar CSS minify settings på samma sätt.
Glöm inte att klicka på knappen Save All Settings för att lagra dina inställningar.
För alternativa metoder, se vår guide om hur du minifierar JavaScript och CSS-filer i WordPress.
Aktivera CDN-stöd i W3 Total Cache
CDN eller content delivery networks hjälper you att ytterligare förbättra din websites prestanda genom att servera statiska filer som gillar images, CSS och JavaScript från ett globalt nätverk av servrar.
Detta minskar belastningen på din WordPress server på webbhotellet och förbättrar sidans laddningshastighet.
W3 Total Caching kommer med built-in support för olika CDN-plattformar.
Vi rekommenderar att du använder Bunny.net som är den bästa CDN-lösningen på marknaden. Det här är vad vi använder för vår OptinMonster website.
Först måste du registrera dig för ett Bunny.net account. När du har registrerat dig måste du skapa en Pull Zone för din website.
En pull-zon add to ett värdnamn till Bunny.net CDN. Det här värdnamnet används sedan för att servera statiska filer för din website.
Add to ett namn för din pull-zon och ange sedan din websites domain name.
När du har lagt till pullzonen måste du besöka sidan Performance ” General Settings.
Sedan rullar du bara ner till CDN section.
Kontrollera boxen Aktivera bredvid alternativet CDN och välj Generic Mirror bredvid alternativet CDN-typ.
Glöm inte att klicka på knappen Save All Changes för att spara dina inställningar.
Därefter måste du besöka CDN-sidan Performance ” och rulla ner till Configuration: Objects section.
Härifrån måste du add to värdnamnet som du skapade tidigare för din pullzone och klicka på knappen test mirror.
W3 Total Caching kontrollerar tillgängligheten av ditt värdnamn och visar Test Passed message när det är utan problem.
Du kan nu klicka på knappen Save All Changes för att spara dina inställningar.
W3 Total Caching kommer nu att börja servera dina statiska resurser från CDN-servern.
W3 Total Caching fungerar också bra med Cloudflare gratis CDN. Alternativt kan du också använda den med Sucuri som är den bästa website firewall-tjänsten med built-in CDN-tjänst.
Felsökning av W3 Total Cache Issues
När du har konfigurerat W3 Total Cache på rätt sätt bör den fungera sömlöst i bakgrunden för att förbättra WordPress hastighet och öka prestandan.
Ibland kan du stöta på issues där du inte ser ändringar som du gjort på din website direkt, eller så kanske ett plugin inte fungerar som det ska.
Den vanligaste orsaken till dessa issues är att you förmodligen ser en gammal cachelagrad version av your website.
Detta kan enkelt fixas genom att cleara cachen i WordPress.
Klicka bara på menyn Performance högst upp och välj sedan alternativet Purge All Caches. W3 Total Cache kommer att cleara all cached content på din website.
Om du fortfarande ser den gamla versionen av din website kan du också prova att cleara webbläsarens cache.
Vi hoppas att den här artikeln hjälpte dig att installera och konfigurera W3 Total Cache i WordPress.

I would recommend everyone to make a note of the changes you have made, especially. Issues on the website may not manifest immediately. For instance, it happened to me that after a week, WordPress started behaving strangely, and it was happening randomly. It took me quite a while to find the problem in the cache plugin and incorrect settings. If I had documented the changes I made, I would have found the problem more easily. It’s a recommendation for everyone.

Hello,
I’ve a question:
Does a free version slow the website ? My opinion is that a free version of this plugin makes website slow.. how do you think?
WPBeginner Support says
The free version of plugins will not slow down your site, poorly coded plugins can slow down your site.

You would want to only use one or the other, if your W3 Total cache minification is working well then stay with that for the moment

Thanks for the great article! I really benefitted from it and have a better performance now 1/4 load time. One thing you should mention is in the Browser Page under Performance tab there is a box at the bottom that says Rewrite URL. Don’t check that it ruined my pages. All links were alterred but I took it off and it’s ok.

Thanks for your very easy to follow tutorial (with screenshots) on W3 Total Cache. I noticed an immediate difference in load time of the site.

Hi, As per your recommendation, I have decided to go for MaxCDN, Is there any new update about CDN? Going to the MaxCDN site, there are different service including Content Delivery Network, Edge Delivery and other. Can your recommend me which service I have to select initially? I have new blog with no affiliate link till now and not planning for the next six month. And I am planning to apply Google adsense in the near future.Presently I installed WP Super Cache.
Do I need to switch W3 Total Cache to configure with MaxCDN? if I can configure MaxCDN with WP Super Cache, do you have any guideline?

Vijay Prajapati says
I am Using W3 Total cache plugin for WordPress. My post has one table which updates every minute/hour. But as I do caching, the server does not serves latest version, instead it displays cached copy to the visitor. How can I purge cache every 30 minutes automatically so that it shows latest version of the post at after every 30 minutes?
I have already tried inserting this code in functions.php file but its not purging cache every 1h, instead it dies 2-3h later.
function w3_flush_cache( ) {
$w3_plugin_totalcache->flush_all();
}
// Schedule Cron Job Event
function w3tc_cache_flush() {
if ( ! wp_next_scheduled( ’w3_flush_cache’ ) ) {
wp_schedule_event( current_time( ’timestamp’ ), ’hourly’, ’w3_flush_cache’ );
}
}
Anna says
Thanks for such an easy to follow article. I broke my website yesterday using instructions from another blog. I should have come here first!!
I am a bit surprised by my results though. I did a Pingdom and GT Metrics test before I made all these changes and my page load time was:
Pingdom: 8.91 secs and GT Metrix: 5.3 secs
After I made all the changes I re-ran the tests:
Pingdom: 9.51 secs and GT Metrix: 9.9 secs
I thought my load times were meant to get much better – not worse!!?? What have I done wrong?
WPBeginner Support says
Hi Anna,
Allow the plugin to generate cache and recheck your scores. If that doesn’t help try to review your cache settings to make sure everything is setup properly. Alternately, you can try WP Super Cache and see if it helps.

Roman says
Thank you for so great content.
Should I enable ”Page cache” option in the process of development of site or only at when I launch it?
For me it is convenient to do this right now, but I think maybe during development it is not good as I visiting thousand times to check the progress.
WPBeginner Support says
Hi Roman,
Yes, you are right. You can set up the plugin later once your website is live.

Hi! Trying to install the W3 Total Cache Plug In, and while it says it is compatible with my version of WordPress, it says that the plug in is unavailable and says ”Not allowed on our system due to performance, security or compatibility concerns. Please contact support with any questions.”
First of all… do you know why this is no longer working? And, do you have an alternative cache plug in that you recommend? Thank you!
WPBeginner Support says
Hi Jessica,
This means that your WordPress hosting company doesn’t allow the plugin. Most probably because they have their own caching solution integrated into your hosting account which doesn’t work well with W3 total Cache. Please contact your hosting provider for more details.

Andy Sellers says
Hi, I need some help please.
I’ve followed the instructions to serve my static files through CDN (and they’re very clear, thank you) and have found the process straightforward so far- but when I log in to my site the URL still starts with ’www.’ and not ’cdn’ so I guess cdn is not operational yet.
One thing I notice is that in the MAXcdn account page there is no option to ’Update’ the Custom Domain settings as mentioned in the instructions – is this OK? I assume it now updates automatically?
But my main problem is that, assuming I now have to do this, I don’t know how to specify the static files in the custom files list in the custom setting of W3Total Cache. Help please. How should I fill in this Advanced panel – it’s now getting a bit too techie for me? Thank you.
WPBeginner Support says
Hi Andy,
You will login to your WordPress site using the normal URL. CDN only serves static files via their network not the whole website.
MaxCDN settings may have changed, but you would still need to setup your domain. Please contact their support and they will be able to guide you.

Derek C says
Thank you so much! I was about to go pay an extra $15 a month for cloud based hosting because my blog had gotten so slow at times it was unbearable! I had setup W3 Total Cache and just enabled everything.
I didn’t recognize it until going through your guide, but this was the main reason my dashboard and WP console was taking FOREVER to do anything. Sometimes I would wait 20-30 seconds just to create or save a post. Now it is like 2-3 seconds at the max. Also, my site loads even faster with a lot of that junk turned off.
I am on a shared hosting plan, and I guess all of the caching was actually bottlenecking the CPU or something…. Anyhow, thanks for such a useful guide!

I downloaded plugin and now its loading slower.
Each time I test in pingdom the % faster than other sites decreases.
Its only a 1 page site at this time.
Ian Smith says
I recently set up W3 Total Cache with the Rackspace Cloud Files CDN. It all works, but I had expected the media files in the wp-content/uploads folder to only be posted in the CDN rather than on the server. Instead, media uploads now go to both the CDN AND the wp-content/uploads folder. Is this what is supposed to happen? It seemed unnecessarily redundant to me.
WPBeginner Support says
Yes, but the images on your server are stored so that you can end using CDN service anytime you want, or move to another service, or to create backup using WordPress backup plugins. However, your visitors will be served images from the closest CDN server instead of your site.

Hi ! I installed yesterday Super Cache because it seemed easier to configure than W3 Total Cache but this morning my site was very very very slow… So I decided to follow your tutorial step by step and change plugins.
So, the first step was to deactivate the first plugin, so I clicked deactivate Super Cache and my whole site crashed !!! I get this message : 503 SERVICE UNAVAILABLE no server is available to handle this request.
I don’t know what to do. Can you help ?

Thank your this tutorial. I have used it for a couple of my sites.
One thing, which might be a ”duh” situation… But, I had my site in ”Maintenance Mode” using SeedProd’s Coming Soon Pro. I did not see the CDN in front of the image urls until I turned off maintenance mode. Then, when I turned it back on again, they were gone again.
Just in case someone needs this information

Hello,
I appreciate so much, your posts. They have helped me learn a bit about setting up my website. However, this particular post led me to check a bunch of boxes under”Performance » Browser Cache” that took me from faster than 91% down to faster than 71% on speed. I had checked them just as you have in your picture above. I unchecked all your suggested boxes and got back to 84%. (on Pingdom) This was the only change I made. I don’t understand why it made things slower, or why I couldn’t get back to my original speed. If you could explain this I would appreciate it. Thanks.
WPBeginner Support says
A lot of reasons can show you conflicting results when you are expecting something different. For example, you may have forgotten to save plugin settings, your server is particularly under heavy traffic at that time. Make sure you enable gzip compression as we have shown above, then test.

However my website is slower then before.

I haven’t enabled database caching and Minify as per your insutrctions as yet…also don’t have CDN service.
before my website was faster.
Any thoughts?

How are you checking your website speed and performance? We recommend testing with pingdom using different locations. If it is still slow, then try resetting the plugin and follow the setup instructions again.

yes using pingdom to test and speed is 2.55s…I think we can do better

THANK YOU FOR MAKING THIS! I’m EXTREMELY cautions on the plugins I install from horror stories. I’ve also heard horror stories about this very plug in. Therefore, I research as much as I can: tutorials, forums, reviews, troubleshooting etc. I am going to follow your tutorial exactly. My server says my site is too large, 500kb, and needs to be gzipped. [sigh] Another plugin to search.
Helpful note: You may have a downloadable instructions on your site somewhere & I am not see it. But It would be helpful if I could download to print OR this was print friendly. you have have link but I am not seeing it.

Hi,
I do have one question, when static pages are created for example you have 200 pages and just installed and set up W3 cache. So now when static pages will be created for all those 200 sites.
Do you have to load it manually every site by site in your browser ? I understand that this action takes some time so when exactly those sites are created ( static copies on a disk) ?
