Your plugin was exactly what I was looking for! Thank you so very much! I'm just having one problem (and I'm not a developer, don't know PHP, I'm self-taught, so please be gentle. :-).
I'm using the Graphene theme and the Graphene mobile theme (which I paid for). Everything works great on a PC, but when I try to open it on my android the style is gone. Only when I disable the Friends Only plugin, does it allow the theme to appear correctly on my mobile device. (Haven't tried iPads yet.) Is there something I can modify to give it permission to access the mobile theme's stylesheet or is that even the problem?
Thanks for any help you can send my way!
UPDATE: It seems to work if I use the WPTouch plugin...so for now that's what I'll do. :-)
