I seem to remember issues with cut off, or missing, buttons on certain browsers... usually on phones. I have a similar issue with EQ upgrades when I haven't yet purchased CEQ. Sometimes the window appears so low you can just barely see the tops of the two buttons "cancel" and "accept". If you can't remember which is which, accept in the one on the right... if you can get your cursor to click on that tiny sliver of the top of the button.

Otherwise, you have to 'hide' the WG bar at the bottom of the page.
