MyBB Community Forums

Hi

Just set a forum up with this MyBB and it works great, but i have one problem when we are going in to read a post and go out then it says that we are logged in with that user then we can try to jump around in other categories and suddenly it says it the right user logged in. but it seems it's only the name that changes when i go in user cp it shows my own user.
any one that can help with any solution?

Thanks in advance

Cheers,
Per
