Today a minor update for Really Simple SSL was released. No major changes:
New option: switch mixed content fixer hook
In most sites the template_redirect hook works fine as hook to fire the mixed content fixer on. But in some cases, due to plugin conflicts, this does not work, resulting in the mixed content fixer not to work. If that happens, in most cases this can be fixed by switching the mixed content fixer to another hook. As of 2.5.20, you can do this using a setting in settings/ssl.
Dismiss activate SSL notice
In very rare edge cases, it is not possible to enable SSL in the normal way. In that case you can still use the mixed content fixer. To dismiss the notice, you can add a constant:
To your wp-config.php.
SSL enabled nag
The notice “SSL enabled” did not dismiss properly on the network menu. This has been fixed.
