Help with blank pages (intermittent)?

Hi

I'm using the latest version of Zen Cart and I've imported my categories and products from an older version of Zen Cart. Some times the shop pages load fine and some times I just get blank pages.

I've run the debug tool and checked the error logs in my cpanel but nothing is alerting me as to what the error could be. My web host is also a bit stumped as to what is happening aswell.

I've built loads of Zen Cart shops and have never run into this problem. All files were uploaded correctly and there is nothing unusual about my server apart from that I run litespeed.

The shop can be found at https://www.lbtoysandgifts.co.uk
I'm not fond of the design but Ive had to make it look like the original site

Any advice would be appreciated.

Thanks

Go edit products_id = 449 and see if you have anything in the products_description like bad html or monster images etc. that might be breaking the display ...
