Product pages no longer working

Hi,

My product category pages no longer work after recently upgrading. They just point to 404 error page. Please see poppy-b.com. I have tried changing themes to the Jigotheme and it is still the same.

Any help or advice very gratefully received.

Thanks

Here is the Jigoshop system info (by the way it says the memory is too low but it has been increased by my host provider)
