Display a list of subspaces of the current space
Problem
When trying to display a list of subspaces of a current space, I also see "No permission" spaces and their subspaces.
Solution
The displaying of "No Permission" is a known issue. We are tracking it in this ticket: https://communardo.atlassian.net/browse/CSSP-163 .
It seems, that if you grant access to single users, the "No Permission" disappears, but as soon as you use groups to restrict the space, it will appear for users without the proper rights. This might explain, why you see only several "No Permission" spaces.
