[Plugin: Plugin Organizer] Warning: dirname() error in Global Plugins option

Warning: dirname() expects parameter 1 to be string, array given in /home/mysite/public_html/project/wp-content/plugins/plugin-organizer/tpl/globalPlugins.php on line 27

…and for me – it doesn’t work at all – all plugins are loading on front-end page (yes I’ve moved MU file).
