I'm currently running an old version of phpbb 3.0.9, and since I use a custom style based on subsilver2 with a lot of mods, I've not had the time to upgrade.
I'd like to change the forum from http to https, and already have the certificate installed and all https request already all work fine.
I've read that changing the forum setting to https and also the cookie settings causes some people to get locked out of admin, which worries me a great deal because I'm not really experienced enough to get the resolved.
So my question is, can I just do a 301 redirect of all http request to https? Will that basically be the same, or is there a reason why a change of forum settings to https is required?
