Missing menu bar from app drawer

[AC Question]

I accidentally hid my menu bar from my app drawer while attempting to unhide an app. Obviously, I was unsuccessful. I have an HTC One M7 and this issue is driving me up a wall. Can't find anything online. Please help.

I'm having the exact same problem and can't find any answers online either. Only difference is I have an S5. Sure would appreciate any info anyone has to offer!
