Migrating to SSL can cause unexpected side effects. When caching is causing redirects, or a plugin redirects back to http, or other such issues, it can be helpful to activate Really Simple SSL in a minimized way (as of 2.5.9).
First, deactivate Really Simple SSL (use the remote script if you don’t have access to the admin), then add the following line to your wp-config.php.
define("RSSSL_SAFE_MODE", true);
After doing so, the plugin will no longer:
- Change your site URL to https
- Add a redirect
One thing will still be active, which is the Mixed Content fixer. You can disable this in the plugin’s settings, at which point the plugin is not actively doing anything.
If your issue doesn’t come back in safe mode you can try to enable the features one by one: the Mixed Content fixer, adding a redirect (Settings -> SSL & Security -> “Settings” in the top menu bar -> SSL) and changing the URL to https (under Settings -> General in WordPress itself) separately, so you can narrow down which one of these causes the problem.
