quick reply is throwing a mysql error, but a standard reply isn't..

[andrewjs18]

as the title says..when I make a quick reply, it throws this error:
MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
1045 - Access denied for user 'uglycars_vehicle'@'localhost' (using password: NO)
Query:
[READ] Unable to connect to MySQL server

but when you hit 'new reply' it seems to work just fine.
