Email login

Hello,

This option is for “Single field form” under “Form pattern” setting.
If you are using separate forms, use this snippet to disable Login with username

add_filter( 'xoo_el_process_login_errors', function( $error, $creds ){
	if( isset( $creds['user_login'] ) && !is_email( $creds['user_login'] ) ){
		$error->add( 'not-allowed', 'Please enter valid email address.' ); 
	}
	return $error;
}, 10, 2 );
