Solution for 'php connect to mysql problem'

Q: I keep getting an Error connecting to database message but I'm sure my configuration is correct.
A: Try resetting your MySQL password manually. If you have access to MySQL via shell, try issuing:

SET PASSWORD FOR 'wordpressusername'@'hostname' = OLD_PASSWORD('password');

note: If you are using a version of MySQL prior to 4.1, use PASSWORD instead of OLD_PASSWORD. If you do not have shell access, you should be able to simply enter the above into an SQL query in phpMyAdmin. Failing that, you may need to use your host's control panel to reset the password for your database user.
