I have the exact same error message on my installation.

Mine has something to do with the server configuration on this Godaddy account. It works fine on the main domain with the exact same configuration of plugins and the same theme as this non-working one on the secondary domain (which has its document root in a sub folder of the main domain).
The error only appears when I have e-commerce enabled in TCP main settings (but it’s needed of course).
More importantly, I do not have the ‘products’ custom post type anymore in this installation.
Is your setup similar to mine?
