The reason is you wont be able to see any video or audio. Also in the forums the functions to post reply and quote dont want to work. This is all from java and getting it to work properly under the firefox browser with this theme that I used. This is the best theme and it was working before so it’s a matter of getting thing tuned in. Another bug is full screen the videos wont go full screen. This will have to be another tweek I have to go in and find. When you use the navagation and sub menus appear please remember there are pages in the root of those sub menus. Other then that enjoy the website.
