The Woo-commerce 2.1 update gave me many errors that were not addressed in the this support form or on the woo-commerce web page "common problems".
DO NOT UPDATE TO THIS 2.1 VERSION QUITE YET.
Problems exist in the admin area as well, all the order detail information is not showing.
I deleted version 2.1 and then did a fresh install the previous version 2.0.20. (as recommended in another support thread).
I did not have a backup, so I had to reenter my woo-commerce settings and re-created the woo-commerce default pages. I took about an hour, I am back in business with 2.0.20.
Good luck to everyone else, and to Woo-Commerce I say- BAD release: I should have been called version 3, and it should have NOT DELETED things. It could of also checked for the "common problems" before install.
Woo-commerce is a great plug-in, this is just a terrible release.
I will be wary and very slow to implement woo-commerce releases from now on.
