Intermittent forbidden/no permission errors
 

I've read this thread about forbidden errors etc. but before I do anything I would like a little advice please.

Myself and my members have received various Forbidden messages over the last week but if we go back and try again we always get through to the page we want.

Do you think this is a different type of problem to what is described in the above mentioned thread?

I have attached a couple of screen shots to show the messages I have received, one was even within the admin panel.

Any help appreciated - many thanks in advance :)
