Can't enter the album after upgrade.

Question

I have iPhone 4S and I upgraded to iOS 7, then I encountered a problem: I can't enter the password for each album (once you enter the main password, you can manage to lock each album with a passcode).

Answer 1

You should never update while items are locked in a vault application, because it's possible the application has problems (just like you have). With every update to the OS, the developers need to check if their software works normally. In this case, it appears the software isn't working properly. You will have to update or check for updates for the application. There is no possible fix for this issue.
