I’ve installed the plugin pop over on WordPress Version 3.3.1 but it doesn’t work.
Only the following plugins are installed and active:
– WordPress Importer
– WPMU DEV Update Notifications
– Popover plugin
– Test Head Footer (this plugin did install together with “Popover plugin”. When I deactivate, then Popover plugin gets deleted.)
WPMU Nelo 2.2.5
I receive the following warning in the backend.
Your active theme: Has the call to <?php wp_head(); ?> but it is not called directly before </head>
