I am doing some work on my forum today and I am noticing that randomly I will login and click on a topic and it will log me out and send me to my site’s homepage.  If I am able to make it into a topic and I click on the forums toolset it will log me out.

I have tried it with multiple accounts and it seems to only be happening with one of them.

I have tried using Firefox and Safari. 

Is there some way to trouble shoot what the problem is?
