Migrate 7.12 to 8.2 issue. Home page error on specific users

This also happens on the User Management Page:

Looks like you have some errors. You need to check custom folder code carefully.

Just from looking at the screen shots, your users haven’t subsribed to their email inboxes and probably have an email widget on their home screen, thus the two related problems. Just a guess without diving deeper.
