Okay, so I have had this issue since I first installed vB 4.0.0 and it has continued to 4.0.1. When I try to edit the Main CSS in the Admin cPanel, there is no way to sub it the changes at the bottom, as if the button has been missed off. I have accached a screen-shot so you can see what I see.
Any help would be greatly appreciated. I have already submitted it as a bug report to no avail so far... who knows what's up with it!!
