Hi all, hoping someone can help me.

I installed a new template (candied apple) for my site which worked great, i've not long started on the site so if anything did go wrong there's not a lot to fix but now i've changed to the new template, the products are all still within their categories but when i actually click into a product it only shows up a blank page.

Any ideas what i did wrong and how i fix it ?

Regards Dave
