If you uploaded your profile cover and it is not showing, you have to go to your preferences and look for the profile cover option. Once you see it check it off and it should be working, i'll provide one screenshot once I am home.

Thankyou, but I already have a picture.

I'm not talking about the picture, like in order to make your cover show you have to click the "use profile cover" at the bottom.
