Selecting from my forums

If I go to 'My', then I can't select a forum or the last post in a forum. The only option appears to be to go to 'Boards', then select an option.

 

Nevermind. I just cleared my internet files, and all is well.

 

Nevermind the nevermind.

I still have the problem from MY.

 

It was happening on multiple machines. I frequently use three different PCs. It hasn't happened lately. THANKS.
