Why is this category failing to display the theme properly?

Question

Please see this link http://www.yolli.com/packaging It is the ONLY category on our store which does not display correctly.

I have checked this category's settings and compared them to the other categories, nothing is missing or incorrect.

It has me stumped, hence this post. I hope one of you guys can point me in the right direction. Many thanks in advance.

Answer 1

It turns out that two of the configurable products had no associated products. So when the theme ran PHP to fetch the lowest price of the associated products and found none, it threw an error which prevented the rest of the page from loading.
