Just changed a page and saved, since then I'm getting this error:
Fatal error: Call to a member function is_restricted_read_role() on a non-object in /.../public_html/wp-content/plugins/user/view/admin/edit.php on line 12
Now I can't save the page anymore.. Deleting the tablerow with the permissions for this page didn't help. Overwriting it with the value of one of my other pages didn't help either..
