Problems with loading on ipad & iphone

Hi

I have recently set up a site www.fcbug.org.au/site but it is having trouble when displaying on ios ipad & iphone, it works fine on desktop and android devices.

I have tried switching off any add-ons I have, like the rotating banner image, the gallery and facebook feed etc, but this makes no difference.

Load time on any other device is normal but any ipad or iphone seems to freeze for sometimes many minutes, once it has eventually loaded it seems to be okay,

any help would be grateful

regards

Luke
