Help! It looks like (potentially from the server timing out when someone waited too long to post a forum thread) an error took down all my sites. How can I restart them and recover from this error? I can't access the sites to log in to restart the application!

The error above might indicate that it's not able to find the sql data provider dll in your bin folder... Do you have access to the folders and can you confirm if the DotNetNuke.SqlDataProvider.dll exists in your bin folder.
Additionally, could you restart your IIS server (this would be possible if you're hosting the site yourself). - If you're not hosting the site, but have ftp access, you could make a change to web.config and reupload to the site and this should effectively restart the site.

I am not hosting the site myself -- but I went in and replaced the dotnetnuke.dll file and it restarted the site fine.

The DotNetNuke.SqlDataProvider.dll does exist in the folder -- from looking around the forums here, this would seem to be caused by a Forum module error identified by this poster in this thread:

Hopefully that can get fixed some time. Thanks for the quick response!
