OK..let's re-cap.
1.Your users that have a Mozilla browser cannot see your forums.
2.Your users that have a Mozilla browser CAN see the forums when they test the themes at
http://www.areamike.com.
if the above is true, then what do you think the problem is? The theme? No. Your site has something wrong with it. If a theme works on one site but not on yours, that does not necessarily mean the theme is not working as it should. Take my above advice and upgrade your Forums for starters.
I am TRYING To help you, but as far as I know you are taking any of my advice.
