when attempting to edit a page through the admin menu, I get this error;

Error: is currently unavailable.

any help would be much appreciated.  cheers

 this version is the initial install :  05.04.04 so no upgrades have taken place.

The site is back up right now and the problem seems to be intermittent.  I downloaded the web.config file and make a blank line change and re-uploaded to force the site to be restarted and it came up.  Don't think the is the real solution, however.
