MyBB Community Forums

Hello guys,
I installed Sucuri Firewall.
Added exception rules to htaccess, did everything perfect now my website is back up but members report me they sign in as another user, also the theme keeps changing.

Do I need to wait a few more for it to fix itself? Have you ever encountered this issue?

Foreign firewalls expected to malfunction with MyBB being they are not designed to perform together by intention.
If you wanna secure your MyBB site you should follow the official way:

My issue is now fixed. It was a cache problem.
