HELP - Database connection has failed cannot login

I have just tried to login and got this message.“Could not connect to the database. Please refer to sugarcrm.log for details.”

I checked my log and can see this.

"Wed Mar 18 20:26:39 2015 [531929][-none-][FATAL] Could not connect to DB server xxxxxxxxxxxxxxxxxxxxxxx as xxxxxxxxxx. port : Access denied for user ‘xxxxxxxxxxxxxxxxxxxxxxxxxx’ (using password: YES)

All my files are still on the server (checked with FTP) - databases are still there checked with PHPmyAdmin

Any clues as to what has happened?

Were any changes made? Have you tried restarting the MySQL service?

Thanks,

Will.

No laughing! I forgot that we were migrating servers, and I was logging in halfway through migration :silly:
