That is interesting. A bad request (or 400) error indicates malformed data. So I suspect the problem is at the University end as it generally indicates a low-level bug in the server or client (unlikely!) or the proxy server at Uni is configured incorrectly (they are complicated beasts). What browser is used at Uni (try a different one)? Is a proxy set up (have a look in the options)? Is it just geologyrocks or are other sites affected? Is it the new site only, or did you get them on the old site also?

You might try http://www.geologyrocks.org as the Uni may be blocking .co.uk...

Bizarre... today it works! Hooray

 The error i was getting was saying

"

But all appears to be working now. Whatever it is appears to be sorted

It all makes sense now....

The phpbb cookies from the old site were still floating around. 

Glad it works!

Aah, that explains it. I'm noticing another problem too... The navigation links on the blue bar at the top of the page (home, forums, about the site etc) keep disappearing, seemingly at random.

 Edit- And where's the 'mark all forums read' button?

You mean these links:

If so, they are supposed to chnage, depending on where you are in the site: otherwise known as a breadcrumb trail. They do need some work though.

Mark all read: *sigh* Something I am coding up as we speak. It was the main thing missing from drupal and I only realised how badly it was needed when I imported all the forum topics over and they were ALL unread!

haha! Found a module that does the mark as read thing (saves me coding it ). I will try it out and upload it as soon as I get chance and this will be by the weekend

Right, a button is now available to mark all forums as read. On the forum front page, the button marks all forums as read. On each sub-forum has a button which will mark all topics in that sub-forum as read.

On the old site, the link also gave you the number of topics unread. to see this information, click "Recent posts" on your personal menu on the left. Topics, pages, etc, with new comments or are simply new will be labelled as "new".

Hope that helps! 

Wonderful!

Still seem to be missing the breadcrumb trail though. Is it only me who doesn't see it? I wouldn't be surprised.
