SSL Fixer makes a few changes to the database in order to fix any insecure links. Effectively fixing the HTTPS redirection and mixed content problems in one click. Precisely speaking it does two things:
<ul>
<li>Modify any insecure links from your wp-config.php file, such as WP_DEFINE() home and siteurl.</li>
<li>Convert all your database’s HTTP links into HTTPS ones, making the requests secure.</li>
</ul>
To make these changes, all you need to do is click the plugin’s “Fix SSL” button.
