Hi,
I am having the same problem. I also noticed that the database user no longer exists so I think there has to be some security hole somewhere.
I used fantastico script to install wp 2.0.4 and the config file has 755 CHMOD set by default.
It is a weird thing, last time it happened all my data base was deleted, this time only the user. This is the reason I think this is a security issue.
Please someone give me some advice,
Tony
