This is probably a temporary issue/change, but just in case. Started a bit ago, happening on most pages, and I turned of AdBlock/removed all customCSS just to make sure it's not on my end. Didn't help.
Also, right as I noticed this happened, I was unable to send a shout to the SB (would just hit Submit and nothing would happen, no not banned). No clue if that's related. I was eventually able to shout.

Edit: The page loads normal, then jumps down (appears to happen every time, site's loading fast so it's hard to catch it and make sure).
Pages not affected: User Dashboard (but customCSS page is), Recent Topics
Edit 2: I don't know a whole lot about CSS etc, but div id="page" appears to encompass the selected area, and the height is about right for the gap. "content" is the actual, well... content :p that's pushed down c:
Hard Refresh = no change.
Edit 3: For when these actually, finally, show up, lol. I was clearing out some old events when this happened, and now my events are broken (no background or divider lines, not able to be cleared). I do have a lot of events. IF it's related, I would like some warning before they are cleared so I can copy/paste or something.
It's been driving me crazy today. You nailed most of the details. Just wanted to confirm it's happening on me too I have firefox and windows 8.1 it may be one of those causing it.
Looks to me like the ad is pushing the page really far down for some reason. This hasn't happened to me, probably because I use adblock, which I know isn't the best thing for the site, but I'm terrified of accidentally clicking on one of the ads or something.
Still, wish something were done to fix this for you.
