Site stopped suddenly auto refreshing
 

Here are some examples:

I add a forum, thread, post, etc - I then go back to the main forum page it does not show up, I go to the actual forum it does not show up, I go the actual thread/post (after supplement post) and nothing shows up.

For each step above I have to refresh the page for it to show up - what have I done wrong - I have tried in both IE and FF with the same results.

Thanks in advance for your kind assistance
