Yes. Is there a way I can get your email? I’m out of town and don’t have access to the site at the moment.

Thanks Edward! It appears to only happen for certain products. One example is the ‘Samba Whistle’ if you try adding that to the cart. Also, I’ve disable shipping at this point because customers were unable to finish checkout, so you won’t see that error.

I had a similar problem and fixed it by turning off “Use Hierarchical Product Category URL” in Settings->Store->General. I would also try disabling and re-enabling the plugin, and updating your permalinks.
