XF 1.5 Keep getitng logged out of forum?


Well-known member
I keep getting logged out of a forum I'm putting together. I always use the www.domain.com address but it keeps logging me out even under this address. This happens periodically and I can't figure out why. I'm the only one experiencing this issue as far as I know (we aren't open yet but my co-admin doesn't have this issue) What could the problem be? I may add I run another forum on XF that's also re-launching soon and I stay logged in just fine on there.
