I randomly got this error and it shows the username for my database.
PDOException: SQLSTATE  Access denied for user '******'@'localhost' (using password: YES) in lock_may_be_available() (line 165 of /home/*****/public_html/******.com/includes/lock.inc).
What exactly do I do? It's completely random. I accessed the site last night. No problems. Now this. Suggestions?
