I receive the following error: Login failed for user 'xxxusername'. I copied the connection string displayed under Database Management in the Control Panel - and replaced the password. I have providerName="System.Data.SqlClient" But continue to get Login failed... This is the same user and password I use to loing to SQL Web Admin.
You could try giving us the connection string, and taking out the exact user/pass obviously. Maybe there's a problem with the format. Otherwise, you might have to write support, as we probably can't help you if we don't know the exact user/pass. On a note, did you replace the password? Usually it's "********" in the connection string from the CP, so you have to change that out for your real password.
