I've seen this asked a few times before,
"Why do I only see 'mySQL' in cPanel?"

The Reason: Your (cPanel) theme is set to an CPSkins Theme

How to Fix: Log into WHM > Modify an Account > Select Account >
Set the Language to "CPSkins-Englsh" > Save.

Now try logging into your cPanel, and it should be fixed


*Note, I'm not sure of the exact list of what is considered
"CPSkins" other than the obvious, "CPSkin."
I'll update this with a list in a few days.
