How/where do I upgrade to a higher php?

That's usually up to your host, but you should be able to put in a request with them.

got this error when looking at an item
"jCarousel: No width/height set for items. This will cause an infinite loop. Aborting.."

Hi there 4x4 Mecca,

Apparently the product detail page on cafepress has slightly adjusted some settings [the similar products scroll window is the jCarousel area].

We're investigating.. stay tuned.

Cheers,

Is anyone else experiencing the issue that 4x4 Mecca has described above?

I received the same message today upon opening an item to purchase. It didn't happen until I clicked on a link to open the individual item.

Ok cool.

Yes I get the same error ...but once you click "OK" on the popup box with the error all works ok.

BTW - I forgot to say thanks for the fix. My users also are appreciating the way it integrates, it has already translated to more sales.

Danke.

Yes I am getting the same error message.

Thanks,
