If you are experiencing the error message above when saving, sending or updating a page on the site then there is most likely a problem at our end.
In order for us to be able to troubleshoot the problem, it would be helpful if we had the exact error message that Internet Explorer is currently hiding from you.
To see the actual error message go to:
Tools - Internet Options - Advanced (tab). Scroll down until you see 'Show friendly HTTP errors'. Make sure that box is not ticked. Then click OK to close that window.
Re-submit your request, the one that was causing the 'Page cannot be displayed' message and you should see the full error message/code.
To send that to us click here and we'll investigate immediately.
