CMS Made Simple Forums

Hello, i have just published a new section on my website which some people with PC or Mac can see and others are telling me that they just get a blank page. These people are people with IIE version 7, 8,9 and XP. They can access other pages on my website without any issues whatsoever, it's only this new section just published 2 days ago that they can't see ( www.kidsinmadrid.com/en/kids-fun-ideas.html)
Does anyone have any idea what the problem might be and how to resolve it?
Thanks in advance!
Paloma

I have tested the page given with IE8, Firefox 3.6, Safari 5.03, Chrome 8.0 and Opera 11. Everything seems OK from here, so it cannot be a general browser problem.
