Hi

This is definitely a bug between LMS and Woo. It may be that the error message is generated by WooCommerce, but that’s not the cause. Here is my argument:

Please test this scenario:
Deactivate LMS plugin.
Access this test products: https://publicconstruction.ro/produs/test/
Go to checkout page: https://publicconstruction.ro/checkout/ and place the order.
Everything works fine.
Activate LMS, try again with test product or the course (https://publicconstruction.ro/courses/curs-manager-de-proiect/) and you’ll get the error.

So, please let’s dive a little bit deeper into the issue since it’s clearly related to how the account creation process through WooCommerce conflicts with LMS.

Thanks
Alex
