I found the issue, it was not related to Enfold.. it was another plugin.
This issue can be closed and deleted, because I don’t think it will help anyone else.
I did some troubleshooting this morning.
I disabled the TEC plugins and switched to the standard theme to verify the behavior. This is what I found:
* “Add to cart” is missing on the normal product pages
* Cart is not being correctly initialized.
When I switched back I also noticed that the “Log in to purchase” is pointing to the wp-login page instead of to the my-account page.
