When you enable the setting “htaccess redirect” in settings/ssl/settings, Really Simple SSL detects the best redirect, then opens a testpage to verify this option won’t result in redirect loops. Even so this in some cases causes redirect loops after all: there are a lot of server configurations, and some respond unexpectedly to the proposed rules. If this happens, you get locked out of the back-end, because of the redirect loop.
To solve this you have to remove the rewrite rule from your .htaccess file.
- Open your ftp client (for example filezilla)
- In the root of your website, look for the .htaccess file. If you cannot find it, make sure filezilla shows hidden files
- Open it in a texteditor, and look for # BEGIN rlrssslReallySimpleSSL
- Remove all lines between # BEGIN and # END, and save
- Prevent Really Simple SSL from editing the htaccess any further:
- Look for wp-config.php in the root of your site.
- Open the wp-config, and add at the top, but after “
define( 'RLRSSSL_DO_NOT_EDIT_HTACCESS', TRUE );
