Automated account creation with empty password

I just debugged an issue that relates to this plugin which I installed to be able to use ACF. I import customer accounts programmatically and let woocommerce create a password. But then your plugin complains about “illegal confirmation password” – since there is none. There is also nothing in _POST in that case.

I just added

if(empty($_POST))
return $validation_errors;

to wooc_validate_extra_register_fields which works fine.
