My user group has the view_offline permission and the system setting site_status is set to "No".
My user group can't view any pages on either context when the site is offline.
If I set the site_status to yes then they can view everything perfectly of course.
Yes, the user group is assigned to both contexts.
Also I just noticed, the admin can't see the front end contexts when the site is offline either.
Admin group is also assigned to both contexts.
Thought it might have been a cookie issue but I've tried multiple browsers and computers.
Do they have the same access-policy for each context?
Did you flush permissions after changing anything?
Could you give us a screenshot,from where you set this up?
