I'm getting a lot of "Session IP/browser/X_FORWARDED_FOR check failed" errors, since we migrated our forum to a new host (86 pages of them since the 21st of March.
There is a topic here
, for an older version of phpBB, where someone suggests this is down to a user upgrading their browser without logging out and back in again, but I'm seeing lots of usernames in the pages I've skimmed.
Does that mean that every time Firefox pushes out an update the error log of my forum is going to fill up with these error messages until I get everyone to log out?
What does "truncating your sessions table to force this along" mean? Would it fix something on the server or kick everyone out?
