Invalid Address

This error refers to woocomerce settings. i found the culprate. When i updated to 4.6, the email field in my woocommerce settings was changed. When i fixed the email, the SMTP email woo was using to send the confirmation checked out and the checkout was able to finalize.

Nice spottting plzshareme ??

plzshareme can you be more specific in your answer. I have the same problem and I want to fix it but I can not. Can you step by step say what did you do?

Thanks
