Forum database error after editing config.php
 

I needed to change my database user password (which i did so using PhpMyAdmin)

i went on to edit the config.php file to update that change and that's when things went wrong.


i'v tried reverting the changes (changed back to the old password) and revert to the old config.php but the database error is still there.

What did i do wrong and what should i do now?
