CMS Styles not switching on the CMS
 

I have been trying to configure the CMS numerous times and I really don't like my CMS style right now and when I change it to BlueFox, it will not change it will stay on the default style and it is really getting annoying now as I really want to change it. So any assistance will be grateful thanks :).

I have tried the default style that vBulletin gives and it will not change to that either (So basically it will not change to any other style).
