Hi, I find the tools UAM and UAM for NEXTGEN great. Unfortunately updating the function "Hide not pictures, etc." works. For a new call to the hook is out again. Unfortunately, you can not lock a single photo for certain user groups as well. This only works for the entire Gallery, although check boxes are available at each photo. I have restarted the server and WP completely rebuilt. Is there a future extension or I have an error. The versions are the latest. Thank you for a speedy reply. Sincerely Jottha Eff.
