Mysql help

Database Error: Unable to connect to the database:Could not connect to MySQL

I am not very experienced and ot sure what I did to cause this?

Are you able to open your database via DH panel --> Goodies --> Mysql?

yes When everything went haywire yesterday i may have changes somthing in mysql … not knowing what I am doing is what got me in this shape

Double check the database hostname, username, and password in your setting files.

I have gotten that error in the past when entering the wrong password in Wordpress settings. (wp-config.php)
