I've got CPG1.5x installed.

Yesterday I uploaded some new pictures and using Yahoo!'s interface made a backup of the database because I thought I'd do an update.
Now it says:
"Coppermine critical error:
Unable to connect to database !
MySQL said: Access denied for user 'sonalicorp'@'localhost' (using password: YES)"
What to do? I didn't change my password.. all I did was upload a few hundred pictures. They were working fine yesterday.
I already solved the problem. It seems I did change my password by mistake when logging into Database Administrator to make the backup. Oops.
