I created a new user group, I already give permissions to view file catalog.

but this user group cannot view it , it can but it says ,"No available entries found "

I really confused , another user groups can view it but this newly created user group can't.

somebody can help me ?

I already solved the problem , this..

I already did what you've told me above and still cannot solve the problem.

then I managed to go to categories management,then check all of my categories one by one.

well,thanks. I solved the problem.
