When viewing the forum in an iPad (using Safari/landscape mode), the footer will not end where it should. Instead it continues to scroll down a good entire screen width, showing nothing but a fully greyed blank screen.
At first I thought it was my forum and some template modification that I made, but the same thing happened when I switched my forum into the "default" mode. I deactivated all the add-ons as well, to no avail.
So I wondered if it was native to Xenforo so I tried the same thing here at Xenforo.com/community/
Same thing. When I view the forum here on an iPad and scroll down to the footer, the footer ends, but the screen does not. I can scroll another entire screen width before the roll stops. I'd give a screenshot but that is nothing but a blank, gray screen.
When I tried this other Xenforo forums, I get the same result.
Yet, when I view both my forum and xenforo.com on Safari on a laptop or a desktop, it renders perfect.
