MyBB Community Forums

I am not quite sure where to post this, but I am the admin of a MyBB forum that I just installed on my site. And Everytime I try and log in, it takes me back to the index, but I am not logged in. Even members can't log in.

Now I read that It is usually due to cookie settings, and the only way I can change that is if I log into the Admin CP, but I can't even log in regularly, I really need help with this please.

As it says in the sticky thread at the top of the forum, if you can't do it in the ACP you have to edit it in ./inc/settings.php and then in the ACP after.
