L’SSL rende sicuro il vostro sito web, ma molti proprietari di siti web incontrano problemi inaspettati quando spostano i loro siti WordPress su SSL o aggiungono un certificato SSL a un sito esistente.
Negli anni in cui abbiamo aiutato le persone con i loro siti WordPress, abbiamo visto e corretto molti problemi SSL che vanno dall’attenzione per i contenuti misti ai problemi di accesso.
Questa guida vi mostrerà come correggere i problemi SSL più comuni in WordPress.
Che cos’è SSL/HTTPS e perché dovreste iniziare a usarlo subito?
SSL è l’abbreviazione di Secure Sockets Layers, una tecnologia di crittografia che crea una connessione sicura tra il browser dell’utente e il vostro server di hosting WordPress.
Una volta abilitato l’SSL, il sito web utilizzerà HTTPS anziché HTTP. Nel browser si vedrà anche un lucchetto o un segno di spunta accanto all’indirizzo del sito web per indicare che è sicuro.
SSL/HTTPS rende più difficile per gli hacker intercettare la connessione. Ogni sito abilitato a SSL/HTTPS riceve un certificato SSL unico a scopo di identificazione.
Se un server finge di essere in HTTPS e il suo certificato non corrisponde, la maggior parte dei browser moderni avvisa l’utente di non connettersi al sito web.
Google incoraggia tutti i proprietari di siti web a utilizzare SSL/HTTPS per migliorare la sicurezza generale del web.
Ecco perché Chrome contrassegna come “Non sicuro” tutti i siti web privi di un certificato SSL.
L’etichetta “Non sicuro” nella barra degli indirizzi del browser dà ai vostri clienti una cattiva impressione della vostra attività. A lato, è necessario abilitare SSL/HTTPS se si vuole avviare un negozio online o utilizzare servizi di pagamento come PayPal, Stripe e Authorize.net.
Considerando i pro e i contro, tutti i siti web WordPress devono passare a SSL/HTTPS.
Se non l’avete ancora fatto, potete leggere la nostra guida su come spostare correttamente WordPress da HTTP a HTTPS per avere istruzioni passo dopo passo.
Consigliato: Consultate la nostra guida su come ottenere un certificato SSL gratuito o acquistate un certificato SSL a prezzo scontato da Domain.com.
Tuttavia, potreste incorrere in alcuni errori di WordPress con il vostro certificato SSL. Vediamo quindi alcuni dei problemi più comuni con SSL/HTTPS in WordPress e come risolverli:
1. Correzione dell’errore NET::ERR_CERT_INVALID
Il messaggio di errore NET::ERR_CERT_INVALID viene visualizzato in Google Chrome. Gli altri browser visualizzano un messaggio leggermente diverso, ma fondamentalmente avverte gli utenti che la connessione al vostro sito web non è sicura.
Questo messaggio di errore SSL indica che il browser web dell’utente non ha accettato il certificato presentato dal sito web. Questo può accadere per una serie di motivi:
- Il certificato SSL viene emesso per un nome di dominio o sottodominio diverso.
- Il certificato è scaduto.
- Il browser non riconosce l’autorità di emissione del certificato.
Se avete acquistato un certificato SSL e avete chiesto al vostro provider di hosting WordPress di installarlo per voi, potete contattarlo per risolvere il problema.
Se il certificato SSL è stato installato manualmente, provare a reinstallarlo o contattare il fornitore del certificato SSL per assistenza.
2. Correzione degli errori di contenuto misto dopo il passaggio a SSL/HTTPS
Gli errori di contenuto misto sono causati da fonti che stanno ancora caricando utilizzando il protocollo HTTP non sicuro negli URL. Queste possono includere risorse come immagini, script o fogli di stile.
In questo caso, non sarà possibile vedere un lucchetto sicuro o l’icona “tune” nella barra degli indirizzi del sito web.
Esistono due modi per risolvere gli errori di contenuto misto SSL/HTTPS in WordPress. Ve li mostriamo entrambi e poi potrete scegliere quello che funziona meglio per voi.
1. Correggere gli errori di contenuto misto in WordPress utilizzando un plugin
Questo metodo è più semplice ed è consigliato ai principianti. Tuttavia, può avere un impatto negativo sulle prestazioni di WordPress, perché il plugin tenta di risolvere gli errori di contenuto misto utilizzando una tecnica di buffering dell’output.
Tuttavia, se si utilizza un plugin di caching, l’impatto sarà solo sul primo caricamento della pagina. I visitatori che ritornano non noteranno alcuna differenza di prestazioni.
Per prima cosa, dovrete assicurarvi di avere un certificato SSL. Se non siete sicuri di averne uno, consultate la nostra guida su come ottenere un certificato SSL gratuito per il vostro sito WordPress.
Quindi, è sufficiente installare e attivare il plugin Really Simple SSL. Per maggiori dettagli, consultate la nostra guida passo-passo su come installare un plugin di WordPress.
Dopo l’attivazione, è necessario visitare la pagina Impostazioni ” SSL dalla dashboard di amministrazione di WordPress per rivedere le impostazioni del plugin. Really Simple SSL funziona subito e si occuperà automaticamente delle impostazioni SSL/HTTPS e della correzione degli errori di contenuto misto.
Per saperne di più, consultate la nostra recensione dettagliata di Really Simple SSL.
2. Correzione manuale degli errori di contenuto misto in WordPress
Questo metodo è più efficace e migliore per le prestazioni del vostro sito web. Tuttavia, richiede la risoluzione manuale dei problemi.
Innanzitutto, è necessario andare su Impostazioni ” Generali e assicurarsi che le opzioni “Indirizzo WordPress” e “Indirizzo del sito” abbiano URL HTTPS.
Se si vedono URL che iniziano con “http”, è necessario modificarli in “https”. Non dimenticate di fare clic sul pulsante “Salva modifiche” per memorizzare le impostazioni.
Successivamente, è necessario trovare i vecchi URL HTTP nel database di WordPress e sostituirli con i nuovi URL HTTPS.
È possibile farlo facilmente installando e attivando il plugin Search & Replace Everything. Per maggiori dettagli, consultate la nostra guida passo-passo su come installare un plugin di WordPress.
Dopo l’attivazione, è necessario visitare la pagina Strumenti ” WP Search & Replace. Nel campo ‘Cerca’, dovete aggiungere l’URL del vostro sito web con HTTP. Successivamente, aggiungere l’URL del sito web con “https” nel campo “Sostituisci”.
Quindi, si deve colpire il pulsante “Anteprima di ricerca e sostituzione” per vedere quali URL saranno sostituiti e premere il pulsante “Sostituisci tutto” per continuare. Il plugin aggiorna ora gli URL nel database di WordPress.
Se si verificano ancora errori di contenuto misto, il passo successivo consiste nel risolvere i problemi relativi agli URL nei file del tema e del plugin di WordPress.
Utilizzando lo strumento di ispezione del browser, è necessario individuare le risorse che causano gli errori e prendere nota dei file del sito web da cui vengono caricati.
Se siete esperti nella modifica dei file di WordPress, potete accedere ai file del tema utilizzando l’FTP o il file manager del vostro hosting web. È necessario modificare ciascun file e sostituire “http” con “https”.
Un’altra alternativa è contattare lo sviluppatore del tema e chiedergli di aggiornarlo. Dovranno utilizzare le migliori pratiche di WordPress per caricare i file, il che risolverà il problema HTTP/HTTPS.
Lo stesso vale per il contenuto misto caricato da un plugin di WordPress. Si sconsiglia di modificare da soli i file del plugin, pertanto è necessario informare lo sviluppatore del plugin e richiedere un aggiornamento. Nel frattempo, potete disabilitare il plugin sul vostro sito o trovare un plugin alternativo.
3. Correzione degli errori di troppi reindirizzamenti dopo il passaggio a SSL/HTTPS
WordPress consente di imporre SSL/HTTPS per l’area di amministrazione inserendo la seguente riga nel file wp-config.php:
define('FORCE_SSL_ADMIN', true);
Tuttavia, in alcuni scenari, questa sola impostazione può causare l’errore“Troppi reindirizzamenti“.
Per risolvere questo problema, è necessario aggiungere il seguente codice al file wp-config.php, subito prima della riga che dice: “Questo è tutto, smettete di modificare! Buon blog”:
define('FORCE_SSL_ADMIN', true);
// in some setups HTTP_X_FORWARDED_PROTO might contain
// a comma-separated list e.g. http,https
// so check for https existence
if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false)
$_SERVER['HTTPS']='on';
4. Correggere il reindirizzamento da HTTP a HTTPS di WordPress
WordPress non reindirizza automaticamente le richieste HTTP a HTTPS, a meno che non glielo diciate voi. Se si utilizza un plugin come Really Simple SSL, questo si occuperà dei reindirizzamenti. Altrimenti, dovrete impostare manualmente i reindirizzamenti.
Per impostare il reindirizzamento da HTTP a HTTPS, è necessario aggiungere il seguente codice al file .htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>

Google may have cached the non-https version of your site, if you’ve submitted your sitemap you can have Google recrawl your site.

Hi,
Thanks for your post. I was able to fix ssl on one of my sites, however, I have another site with the woocommerce plugin and, with these steps, I couldn’t solve the problem.
I tried to deactivate all the plugins and when I deactivate the woocommerce my site works fine.
The problem is “too many redirects” and with this the page does not load.
Can anyone give me some tips on how to solve the redirects issue in the woocommerce plugin?

I appreciate all your guidance in this post, my truggle is taht I redirect the URLs in WP General Settings, while the status of SSL Certificate wasn’t active so now I can’t access to My Wordpress administration it appears the NET::ERR_CERT_COMMON_NAME_INVALID error, so I already call my webhosting to fix the SSL Certificate issiue and it will get fixed, but now I wonder if there is a chance that I cand revert the URL to HTTP in CPANEL, so I can word on the design of my webpages…
Please Help Me

If you don’t want to wait for the SSL certificate to be active, you would go into your phpMyAdmin and edit your Options table to revert the site url and home url. https://www.wpbeginner.com/beginners-guide/beginners-guide-to-wordpress-database-management-with-phpmyadmin/

Having problems opening my site on firefox and safari. I’ve installed SSL on one of my domains and the had it verified from the godaddy support team. They said that the ssl is installed fine. But my site doesn’t show the padlock on firefox and safari and sometimes it doesn’t even open.
WPBeginner Support
Your browser may have cached the pre SSL address which could be the cause of your issue.

I did all this. Set up my SSL certificate, installed and activated Really Simple, fixed the mixed content errors (or tried to) with Better Search & Replace and SSL Insecure Content Fixer. However, most of my images are still broken or not loading. They don’t even appear in my media library. The console points to the same file causing the problem—but it’s a file that flat-out does not exist. I cannot find this file anywhere, yet somehow it’s the source of all my images being broken.

Hi guys, first of all, thanks for your great job sharing your knowledge with noobs like me
I’ve just done all the SSL certificate stuff for the first time and got something that seems weird.On the browser that I’ve created the WordPress site and done everything, the website displays just fine . The connection appears to be fully secure and green. But when opening on any other browser or machine, it displays like rubbish. Also, here I get a “Your connection to this site is not fully secure”. When using the Inspect tool, I get 6 of those mixed content errors.
Can you cast some light upon my ignorance, please? Thanks a lot!
WPBeginner Support
You may want to ensure you clear all caching for your site and it can take some time for the SSL to fully update

So.. According to #2 I changed the http to https:, so since than error 404 appears when I try to visit the site with http, if I try with https, than it tells me that this is not a secure site, and it gets blocked.
I need a solution ASAP, please!!!!

It sounds like your SSL isn’t active for your site, you would likely want to reach out to your hosting provider to ensure the certificate is active.

Are there ways to fix issues like these if you cannot access the WordPress dashboard? Very often, if there is an SSL issue, the web browser will not even let you access the login page. I would assume you should be able to manually replace links in the database without using a plugin.

I have a web site that I installed Real Simple SSL and Better Search and Replace plugins. I activated both, and ran the Better Search and Replace tool. My problem is when I go to login I get the message (The page isn’t redirecting properly An error occurred during a connection)
This is in the most recent version of Firefox and I cleared cookies and cache.
I also tried this in Safari and it said that “Too many redirects occurred This might occur if you open a page that is redirected to open another page which then is redirecterd to open the original page.
What should I change or search for to get the wp-admin login page to work properly?

I changed my WordPress Address (URL) and Site Address (URL) from HTTP to HTTPS.
I don’t have any SSL certificate and did not make any other change…i already made the mistake before i saw your article.
Now i cant access my domain and my website is inaccessbile and showing ERR_SSL_PROTOCOL_ERROR
Please, what’s the solution?
WPBeginner Support
You would want to go into your database in the options table as one option to set the addresses back: https://www.wpbeginner.com/beginners-guide/beginners-guide-to-wordpress-database-management-with-phpmyadmin/
Or you can add code to to your wp-config file to change the address, the required code can be found in our article here: https://www.wpbeginner.com/wp-tutorials/how-to-fix-wordpress-login-page-refreshing-and-redirecting-issue/
