Hello,
You asked us only about the info message in this topic. And only this info message is related to WooCommerce part. This your answer and quote of the WooCommerce support http://prntscr.com/os6xdx clearly explains that you asked them about 404 page. That’s why they redirected you to our support.
I don’t understand why did you ask them about 404 page if you got the answer to this question from the very beginning here https://www.8theme.com/topic/404-page-questions/
Anyway, I just ask you to be more attentive while creating topics and getting the answers to avoid misunderstanding in the future.
Regards
