I have a problem with the checkout part of my website. No matter how I try to finalize an order (with a loged existed user or withouth registration) at the moment that I complete the last required field of the billing form i get an “Incorrect login (no username). Contact the site administrator.” error. Funny thing is that if I hit the “Place the order” button, the order is created and everything works just fine so the error message above is just an alert message not an actual error of woocommerce but I cannot mannage to get rid of it.
Maybe you could help me with that.
