Can't access iTunes store via iPhone

[exsheeple]

After I jb my phone; I can no longer access the iTunes store from my phone. When I pull it up, select something to download, tap install, it goes back to the home screen. Can this be fixed?

You need another restore again, somehow your appstore app gets corrupte

I tried like 3 times. I can install before jb but after jb, it's a no go
