No Access when 'subscribers' log in

Hi, so this is an issue that just recently started happening.

When I have people designated as 'subscribers' log in, they now go to a page where it says they don't have access. Prior to just a couple of days ago, this never happened before. They should go to the main page when they can see the training we offer, but they can't.

Any help you could provide on this? VERY important?
