Whoops! Your session has expired

[loganwest]

What is the URL of your site where this unusual problem is allegedly taking place?

I'm having a similar problem with a Zen-Cart installation at:

http://www.tsilaorganics.com/catalog-new/

I've got the COWOA plugin installed and I think my problem might be related to that. But I've uninstalled and reinstalled that plugin and can't find where the issue is.

To test it, add a product to your cart by going here:
http://www.tsilaorganics.com/catalog...roducts_id=225

And when you get to the cart page, you'll get the "Whoops! Your session has expired" error. I've been searching and searching and can't find any solutions for this. Any help someone could offer would be very much appreciated.

Thanks.
Joe
