Constantly getting logged out

Why is it now that everytime I'm on a thread reading through then click home, I have to log back in to view anything. It's kind of annoying having to login every 10 seconds :banghead:

I'm not sure if anyone else has this problem or if it's just me :huh:

Ah nice one Kyle!

 

i posted that thread and at the end of it there i thought i had it worked out, but nope. Is still have to log on constantly, a pain in the ass.
I've eliminated the possibility of it being my end as ive tried it on loads of different computers.
