How to Fix Common SSL Issues in WordPress (Beginner’s Guide)

Moving a WordPress site to SSL can sometime result in unexpected issues. If you’re adding SSL to an existing WordPress site and are running into errors, then you’re in luck. In this guide, we will cover how to fix the most common issues with SSL / HTTPs in WordPress.

Fixing common HTTPS / SSL issues in WordPress

What is SSL / HTTPS and Why You Should Start Using it Right Away?

SSL / HTTPS is an encryption method that secures the connection between users’ browser and your WordPress hosting server. This makes it harder for hackers to eavesdrop on the connection.

Each SSL / HTTPS enabled site is issued a unique SSL certificate for identification purposes. If a server is pretending to be on HTTPS, and its certificate doesn’t match, then most modern browsers will warn the user from connecting to the website.

Insecure connection warning

Google encourages all website owners to use SSL / HTTPS in order to improve overall web security.

That’s why Google’s Chrome web browser marks all websites without an SSL certificate as “Not Secure”.

Chrome HTTP not secure

The ‘Not Secure’ label in the browser’s address bar gives a bad impression to your customers about your business.

Aside from that, you also need SSL / HTTPS enabled if you want to make an online store or want to use payment services like PayPal, Stripe,, etc.

Considering the pros and cons, all websites need to switch to SSL / HTTPS.

If you haven’t already done that, then head over to our guide on how to properly move WordPress from HTTP to HTTPs for step by step instructions.

That being said, let’s take a look at some of the common issues with SSL/HTTPS in WordPress and how to fix them.


This error message appears in Google Chrome. Other browsers display this error with a slightly different message, but it basically warn users that their connection to your website is insecure.

Certificate authority invalid error

This error message indicates that users’ browser didn’t accept the certificate presented by the website. This could happen due to a number of reasons:

  • The SSL certificate is issued to a different domain name or subdomain.
  • The certificate has expired.
  • Your browser doesn’t recognize certificate issuing authority.

If you purchased an SSL certificate and asked your WordPress hosting provider to install it for you, then you can contact them to fix it for you.

If you manually installed SSL certificate, then try reinstalling it or contact your SSL certificate provider for support.

2. Fix Mixed Content Errors After Moving WordPress to SSL / HTTPS

Mixed content errors are caused by sources (images, scripts, or stylesheets) that are still loading using the insecure HTTP protocol in the URLs.

If that is the case, then you will not be able to see a secure padlock icon in your website’s address bar.

Not secure

There are two ways to fix SSL / HTTPS mixed content errors in WordPress. We will show you both of them and then you can pick one that works best for you.

1. Fixed mixed content errors in WordPress using a Plugin

This method is easier and is recommended for beginners.

First, you’ll need to make sure you have an SSL certificate. If you’re not sure if you have one, see our guide on how to get a free SSL certificate for your WordPress website.

Then, simply install and activate the Really Simple SSL plugin. For more details, see our step by step guide on how to install a WordPress plugin.

Upon activation, you need to visit Settings » SSL page to review plugin settings. Really Simple SSL works out of the box and will automatically take care of SSL / HTTPS settings and fix mixed content errors.

Really Simple SSL settings

Note: The plugin attempts to fix mixed content errors by using output buffering technique. This can have a negative performance impact on your site. However, if you are using a caching plugin, then it will only impact the first page load.

2. Manually Fixed Mixed Content Errors in WordPress

This method requires manual troubleshooting, but it is more effective and better for performance.

First, you need to make sure that you are using HTTPS in WordPress settings. Go to Settings » General page and make sure that WordPress Address and Site Address options have HTTPS URLs.

WordPress URL settings

If you see URLs starting with HTTP, then you need to go ahead and change them to HTTPS. Don’t forget to click on the save changes button to store your settings.

Next, you need to find old HTTP URLs in your WordPress database and replace them with the new HTTPS URLs.

You can easily do that by installing and activating the Better Search Replace plugin. For more details, see our step by step guide on how to install a WordPress plugin.

Upon activation, you need to visit Tools » Better Search Replace page. In the ‘Search’ field, you need to add your website URL with HTTP. After that, add your website URL with https in the ‘Replace’ field.

Search and replace URLs in database

The plugin will now update URLs in your WordPress database.

If you are still seeing mixed content errors, then the next step is to troubleshoot URLs in your WordPress theme and plugins.

Using your browser’s Inspect tool, you will need to locate the resources causing the errors and where they are loading from.

Using inspect tool to locate mixed content errors

For theme resources, you will need to find them in your WordPress theme and replace HTTP with HTTPS.

This part can be a bit difficult for beginners as they will have to look for the URLs in all theme files.

If you are unable to find them yourself, then you can also reach out to theme developer and request them to update their theme. They will need to use WordPress best practices to load files, which will fix the HTTP/HTTPS issue.

Same goes for the mixed content loaded by a WordPress plugin. We don’t recommend editing plugin files yourself to change the URLs. You should notify the plugin developer and request them for an update. Meanwhile, you can disable the plugin on your site or find an alternative plugin.

3. Fix Too Many Redirects Errors After Moving to SSL / HTTPS

WordPress allows you to enforce SSL / HTTPS for the admin area by entering the following line into your wp-config.php file.

define('FORCE_SSL_ADMIN', true);

However, in some scenarios this setting alone would cause ‘Too many redirects‘ error. To fix this, you will need to add the following code to your wp-config.php file just before the line that says ‘That’s all, stop editing! Happy blogging.’.

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)

4. Fix WordPress HTTP to HTTPS Redirect

WordPress will not automatically redirect HTTP requests to HTTPS unless you tell it to do so. If you are using a plugin like Really Simple SSL, then it would take care of redirects. Otherwise, you will have to manually set up redirects.

To set up HTTP to HTTPS redirect, you need to add the following code to your .htaccess file.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

  10. Hi,

  11. Hello,

    I recently asked my provider to turn my ( WordPress) website into https. Ever since, my website (including the wp-admin backoffice) has a very long loading time on mobile devices, a few minutes. Desktop is fine.

    Is this a typical problem? Any suggestions? Thanks in advance!

  12. hi dude i wanna ask…

  13. My website is showing this message. How to resolve this issue? Please help!!
    This site can’t provide a secure connection ×××.com uses an unsupported protocol.

    • You would want to reach out to your hosting provider to ensure there are no issues with your SSL certificate.


  14. Thank you so much sir. My problem of “Info/Not Secure” of SSL is solved with this Amazing Article. Thank you so much.

    Keep helping us.

  15. Brilliant! Not often you run into a tutorial that just does exactly what it says!
    Site now secured! ;)

  16. Thanks a lot. I did all the steps from other sources but they didn’t have more detailed stuff to search for errors. Like looking into console to find errors. Seems obvious but well. Thanks a lot!

  17. Very helpful information.
    Especially, the plugin “better search replace” helped me a lot.
    Thank you so much.

  18. After i activate the plugin and load the website, the page appears not secure on the first load. However, when i refresh the page, it shows the page as secure. This issue happens every time :/

  19. When I search my Website directly on Google it shows site not secured sign but when I search it with adding https: then it shows secured sign. So is my site secured or not , I am confused

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


  20. 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?

  21. Hello,

    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

  22. 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.

    • Your browser may have cached the pre SSL address which could be the cause of your issue.


  23. 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.

  24. 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!

    • You may want to ensure you clear all caching for your site and it can take some time for the SSL to fully update


  25. 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.


  26. 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.

    • For a starting point, we recommend reaching out to your hosting provider and they can normally help with some of the issues to allow you to log in to your site.


  27. 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?

  28. 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?
