Follow that tutorial if you're on Stoli and I will guarantee that if you did it right, mysql will work.
The reason the account management panel shows the wrong status is because the server is no longer at localhost - it's at mysql.x10hosting.com, and the management panel hasn't been updated to reflect that.
And as of right now MySQL on Stoli is up - my site loads just fine, and it's almost entirely MySQL driven.
If you're not on Stoli, then my mistake, and this entire post is useless. You can see if you're on stoli in the account management panel; if you are, follow the directions in the post I linked to, and you should be fine
