   Great info as always!

   I’m with Siteground so have SG Optimizer on my site. I’ve gone through the settings as much as I understand, but still getting the Eliminate render-blocking resources.

   Can I use Autoptimize as well, or will it clash with SG? Thanks

     You should be able to use Autoptimize with SG Optimizer but if you have any concerns if you reach out to the plugin’s support they should be able to let you know if there are currently any conflicts between the two

   how can i Fix Render-Blocking JavaScript and CSS in WordPress without a plugin.

   返信

   • WPBeginner Support

     You would need to manually go through the code and set the CSS and JS files to load after the content is added to the page.

   Hi WP Beginner Team,

   Thanks a lot for sharing such a useful article. Autoptimize is an awesome plugin.

   I was looking for a plugin to boost the speed of my wp blog. After reading this post, I installed and activated “Autoptimize” on my blog. And to my surprise it increased the speed of my blog from 39 to 61 for mobile and 76 to 95 for desktop checked on PageSpeed Insights.

   Thank once again for guiding new bloggers like me.

     If you use Google Page insights then there is a dropdown arrow which will show you the URLs that are causing the problem with a learn more link for how to find the url without their tool.

      Hi Deeksha,

      Both plugins are quite safe. If you are seeing inappropriate content on your website, then please make sure that your website is not hacked. You can disable both plugins at any time.

      Sumit:

      The plugin is not working so you need to rename the plugin folder to turn it off. You need ftp or a file manager plugin. Can you access the dashboard via your wp-login.php location? Like domain/wp-login.php

    Hi there. I’ve tried the W3 method and as soon as I turn on Minify (using Disk) I get this:
    Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0

    How does one fix that?

    Great tutorial though overall! Thanks for this.

    返信

    • Gaurav Areng Chakraverti

      EDIT: This problem goes away when I deactivate Autoptimize, however, so does the rest of the site. Only the bare bones remain with no actual content.

      返信

16. David

    The settings for Autoptimize has changed. The only JavaScript Options available is Optimise JavaScript Code? The rest of the options in your screenshot is not available, at least not on the one I have. Last time I tried W3 Total Cache, nobody could access the site. I am still looking for a way of solving the load time of the page, which for some reason stand at anything from 10 – 17 seconds.

    返信

    • Chris

      David, try Gmetrix web speed tool. On the results list there is a waterfall chart showing how the site loads and what the largest files and scripts slowing the page load.
      I find the slowest scripts are googles cdn scripts like google fonts! The very same company insisting, forcing users to their demands have to scripts taking an age to load. You couldn’t make it up.

    Can you use minify on w3 total cache simultaneously with cloudflare? We are using minify in cloudflare and left it disabled in w3cache. But we still keep getting the message- Eliminate render-blocking JavaScript and CSS in above-the-fold content.

    Thanks!

    返信

18. Rana Jayant

    The plugin 23 cache UI has been changed and it doesn’t have any option where we can put our .js URL for optmization.
    I am talking about “Now head over to your WordPress admin area and go to Performance » Minify page.”

    返信

19. MATTY

    Great tutorial. However is W3 Total cache safe to use now due to an issue earlier in the year? I’ve stopped using it since but it was the best plugin out there.

    Thanks for sharing this article but you said (please keep in mind that it can also affect the performance or appearance of your website)
    Please clarify if this effect will be good or bad for the website google ranking?

    返信

    • WPBeginner Support

      Hi Mohamed,

      A faster website is certainly good for SEO rankings. However, when fixing render blocking issues you may end up changing appearance of your theme or get even a lower page speed score than before.

    Ha, funny.

    I was looking for help here.
    then I did the google speed tool for YOUR post here.

    Google result

    mobile Poor
    54 / 100

    desktop
    Needs Work
    66 / 100

    Do you have any clue at all?

    返信

      Hi Angie,

      Often people obsess about getting a perfect 100 with Google PageSpeed which is nearly impossible for most functional websites. If you have any sort of social media buttons, retargeting scripts, or ads, then your site will never get a perfect score.

      Chances are that you’ll be far from it. But that’s why you have other tools like Pingdom to verify your speed results.

      For example: WPBeginner.com homepage loads in 508 ms (which is insanely fast) –
      https://www.wpbeginner.com/wp-content/uploads/2017/11/screenshot1.png

      But has a Google Pagespeed score of 74 on desktop (which those who don’t know any better will consider it to be bad). –
      https://www.wpbeginner.com/wp-content/uploads/2017/11/screenshot2.png

      If you look through all popular websites like ESPN, NYTimes, TechCrunch, etc you’d notice that none of them have a perfect score .. actually far from it.

      Here’s an example of ESPN score – 62 on desktop –
      https://www.wpbeginner.com/wp-content/uploads/2017/11/screenshot3.png

      Here’s an example of NYTimes – 68 on desktop –
      https://www.wpbeginner.com/wp-content/uploads/2017/11/screenshot4.png

      Here’s an example of TechCrunch – 49 on desktop –
      https://www.wpbeginner.com/wp-content/uploads/2017/11/screenshot5.png

      Our advice is to focus on making your website as fast as possible by following our guide on how to speed up WordPress and use tools like Pingdom as a reference point for what your users will see when they load your website.

    This has actually made my render blocking worse. How do we remove it?

    返信

23. Chris Daly

    Every single time I use Autoptimize or W# Total Cache my site explodes. The mobile web view gets trashed into an html menu list and parts of the site stop working. I have tried each of these on 4 different sites and dropped both of them.

    返信

    • Chris

      Chris I suggest you read and adhere to the W3 Cache warning on the minify section. Minify html and css only and again be wary not all css should be mini-fied due to the reasons stated in the post above.
      I use W3 Cache selectively, tinyjpg for image optimisation, and set OpCache in the .htaccess file. Templaters love to use Sliders…but they bloat the page with images screen width at 1920pxs. Ditch the sliders, smaller images (with a modal box if greater detail required) and icons instead.

    I just installed and it broke my homepage. All the images are gone.

    Hey guys! I’ve loved the W3 tutorial. There’s just one information missing: The Embed Location for the JS File Management.

    Is it “Embed before Body”? Or “embed in Head”? Or “Embed after Body”?

    I got 3 new websites down to almost 500 ms, faster than 96% of sites on Pingdom. Similar for other speed testers.

    Thought great, till Google brought me back down to earth with their page insights. Mainly low score for mobile, but thought these modern themes are meant to be responsive? Obviously not!

    I squeezed every image down to next to nothing before uploading as well, so it is frustrating.

    Also, none of the apps work for me with Browser Cache, etc.

    I’d say the same three problems I have – once the basics are done – are:
    1. Render blocking Javascript.
    2. Browser caching.
    3. Images wrong size for mobile.

    When I installed Autoptimize, as suggested in this article, it completely screwed up my website. Maybe I set it up wrong, but after removing it entirely, I reached a Google PageSpeed score of 92 for desktop. Mobile is at 67, so I’m working on improving that, but won’t be using Autoptimize again, that’s for sure!

    Ok I did the steps and installed W3 & went thru the total beginners guide. I also added the edge on W3 although it is in beta and went back and changed from embed the JS before the /body to embed the JS in the head. I now have my desktop speed at 75 (was at 69). And mobile is at 50 (was at 38). Google speed is still saying I need to minify, etc etc. Any other hints or tips or plugins?? Thanks for the help so far

      Hey Rajan,

      You need to first enable minification and click on the save all settings button. After that you need to go to Performance > Minify page. This is where you will find the manual JS minify settings.
