I have perm. to install & manage add-ons.
I can access the install page, BUT AFTER the installation, i'm getting
You do not have permission to view this page or perform this action.
If i go now to "list all add-ons" i can see that the add-on was installed.
So bug is: after installation i'm getting an "no perm" error even i have permissions and the add-on gets installed
