Problems with Other Virtual Servers in Server?

Hey guys!

Love the software, been using it a year now and never looked back!

Having an issue today with the server however.

I have been trying to edit users / virtual server on any of my VS's, and I get an error:

DBI connect failed : Access denied for user 'dernierevie'@'localhost' (using password: YES)

dernierevie is a disabled virtual server that isn't the top level VS.

I want to delete this VS, but I'm afraid to because it may cause things to stop!

Any suggestions would be so helpful! Thanks!
