Blank page when adding item to cart - Help!

Hello all, really hate to start my time here with a problem but, that is how it goes sometimes.

At any rate, a search for "blank page add to cart" came up far too many threads that didn't seem to address the problem I'm having. And I chose this thread because it may very well be a customization issue.

Am trying to set up this cart for a friend of mine and when I try to add an item to the cart I'm faced with a blank page.

The store is at: http://www.glassartinfusion.com/store/

The only item that has been placed as "in stick" is the Dichroic - fushia & bright purple

So you know, it also happens if I only have one (1) product in a category. Click on "Bowls" to see what I mean.

Can anyone help?

Search for blank page in the tutorials/faq's link at the top of this page

Thanks kobra, I did just that and found something helpful. Would be even more so if I was a PHP guy :)

Would it do any good to post the error log message?

Yes it helps
