has anyone else had this problem ?

I use an iPad, with no problems on any site other than the betfair sportsbook homepage ( and its links), and the paddypower homepage. I've tried all the usual remedies including clearing c&cs, off and on, and resetting, but all I get is a white screen below the top bars. Neither companies helplines can help.I can place bets for pp via the odds checker site generally, and can view my pp account via their promotions page, but no matter what routes I take the two sites home pages just show white.Has anyone heard of this? I would have posted on the more popular racing forum but there can be some unpleasant replies nowadays, though I imagine things will improve there after last weeks antics.
