One specific site in Safari, HFBoards, brings up an add on the bottom of the screen:
It is only on this site. If I go to another site in a different tab, then I do not get the ad on the bottom. Also, if I open the site up with Chrome, I do not get the ad on the bottom. I checked the settings, and I havent noticed anything that gives me an option to remove it. The iPad is jailbroken, but I do not think anything that I have installed is causing this problem.
The second issue I have is with Youtube. I live in Greece, and I do not have the fastest internet (10mb/s), but even so, when I try to move forward in a video, even one that is only a few minutes long, I get the spinning logo in the middle, and the video just freezes until its fully loaded.
Any thoughts as to why?
