Hallelujah! What I did was switch off the advertising for your account. @PushPurrCatPaws mentioned codes and css and you said you had no issue on other sites on the platform, so I figured it must be a rogue ad. It's going to be hard to track down the ad that's causing this so we'll just leave your ads switched off until after we move to a new platform (and new ad servers).
