Hi !
I usually install few plugins to my Wordpress installations, but I have one that I'm really used to and it seems that there's a compatibility issue with it.
Plugin link : http://wordpress.org/extend/plugins/user-access-manager/
I use it to manage my users into groups and then hide specific pages from the navigation and prevent access to users that don't belong into the required group.
While it works fine with most of the generic themes, yours seems to use a different navigation system and the pages that should be hidden are still being displayed on the navigation (cosmetic issue).
Could you have a quick look at it to see if that's easily fixable or if that's too much work ?
Thank you !
