Wrong usage of “admin_body_class” filter.

Hi Guys,

You have the wrong usage of admin_body_class filter, and you broke all plugin, which tries to use this filter to add some CSS class to the body tag.

This file:

wp-content/plugins/forms-for-campaign-monitor/forms/core/Application.phpforms/core/Application.php

have add_filter definition:


808 ?···?···add_filter('admin_body_class', array(__CLASS__, 'addBodyClass'));


Which call this function:


1075 ?···public static function addBodyClass()
1076 ?···{
1077
1078 ?···}


And the issue is:

add_filter function must have at least one param, and MUST return this param. In this situation, current admin body class become null.

Please remove this filter or change function into:


1075 ?···public static function addBodyClass( $classes )
1076 ?···{
1077 return $classes;
1078 ?···}


Thank you in advance!
