I hope someone can help me with this?

My magento go site has a gap down the right hand side when viewed on an ipad. It looks fine on a computer

As A new user I can't post a url, but you need to view the site on an ipad to be able to suggest a solution so I hope putting it here without the domain on the end is ok?


Plus .co.uk

I usually find my way through trial and error with Firebug but I cant use it on the ipad.
I have tried firebug lite but I just can't seem to make it work.

Can anyone tell me what I need to change to correct this gap when viewed on an iPad please?
