When you try to switch to a secure HTTPS connection on your WordPress site, you may encounter a so-called "mixed content". This is when a page tries to load secured (HTTPS) and unsecured (HTTP) resources at the same time. This causes browsers to display a security warning, which may scare away your users. So how do you fix the mixed content error in WordPress? Below are some possible solutions.
1. Manually changing links in content
If the mixed content error only appears on a few pages, the simplest solution may be to manually change the links in the content. To do this, you need to find all the links on the page that start with “http://” and change them to “https://”. Note, however, that this approach may be time-consuming and ineffective if the error occurs on multiple pages or if links are embedded in the page's code.
2. Use the Really Simple SSL plugin
Really Simple SSL is a WordPress plugin that automatically detects and corrects mixed content errors. Once installed and activated, the plugin redirects all traffic to the HTTPS version of the site and updates all resources on the site to HTTPS. This is a great solution that eliminates the need to manually search and edit links on the website.
3. Use your browser's developer tools
Developer tools available in browsers like Chrome and Firefox can help you identify resources that are loaded using HTTP. You can open these tools, go to the “Network” section and refresh the page. All resources that are loaded via HTTP will be highlighted. You can then manually update these resources to HTTPS.
4. Changing the settings in the .htaccess file
Another approach is to make changes to the .htaccess file, which controls how the server handles different types of queries. You can add code to your .htaccess file that forces all resources to use HTTPS. Please note that this method should only be used by advanced users, as improper changes to the .htaccess file may cause problems with the website.
5. Use the SSL Insecure Content Fixer plugin
SSL Insecure Content Fixer is another plugin that can help you solve the problem. Once installed and activated, the plugin scans the page for resources loaded via HTTP and updates them to HTTPS.
Remember that migrating to HTTPS is an important step towards increasing the security of your WordPress site. While it may take some effort to fix the mixed content error, the benefits of securing your site and building trust with your users are worth it.
