Sometimes when I try to log in, it takes me back to the index screen not logged in, yet when I go to see Who's Online...

It says I'm online. Now, this wouldn't be a bad thing if it weren't for the fact that when I actually do log in on a second try, it acts as if there's no new posts or any new topics (none of the topics are highlighted), which is slightly inconvenient.

Thoughts or solutions?
