Hello!
We recently added CloudFlare to our site in response to a DDoS attack. At the same time, I installed the CloudFlare IP extension for PHPBB. Since then, users have had persistent login issues, specifically "The submitted forum was invalid..." errors.
I've completely disabled the CloudFlare cache but it hasn't fixed the problem. Disabling the CloudFlare proxy altogether does fix the issue, but that's not really an option, since we've been DDoS'ed to the point our host almost shut us down. What can I do to fix this?
