A clients website, running DNN 04.09.04 has suddenly developed a problem in the last couple of days.

When logged in we can't add a new page, or edit the settings for an existing page (page name, title, keywords etc.) - after clicking 'update' the page just sits there until the following error message pops up: sys.webforms.pagerequestmanager.timeoutexception: The server request timed out.

From a quick google this seems to be an ajax error - however I think this is a red herring, as we can still edit modules, delete pages, add new users etc. It just seems to be page admin functions that time out.

I'm completely baffled. Does anyone have any ideas of what might be happening?

Thanks Will - sorry for the late reply, have had a few days off!

We're not using pageblaster or any modules similar to it, so it may well be something to do with IIS - I'll have a chat with our engineers and see if they've been up to mischief with the server...

I'll also update DNN to 04.09.05!

Many thanks for responding :-)

Thanks for replying Sebastian,

So far we've updated to 4.09.05, checked the transaction log - they were a reasonable size but we've truncated them anyway, same for the EventLog & ScheduleHistory - only a few hundred entries but we've cleared them.

Sadly it's made no difference to the editing or creating pages... although the site itself does seem faster and more responsive.

I'm running out of ideas with this :-(
