Why do site admins get "You are not authorized to access this page" when accessing store-a

I know this was asked in another place, but all the responses were from inactive members so I wasn't sure if I'd ever get an answer, so I apologize if I'm not posting in the correct spot.

After creating a new blog template, new site admins cannot manage their store when they try to access their "store-admin" page. The admin is logged in, but they just can't see the admin page any more. It worked previously for me, but I'm unsure of what I did. :slight_frown: Any suggestions?
