Great reviews of your plugin on wpmu.org. Excited to get it going.
I'm on WP 3.2.1
And I have just installed W3 Total Cache.
Plugin installs, and can be activated. But when I click it under Settings, I get this:
Fatal error: Call to undefined method stdClass::add_help_tab() in ..... wp-content/plugins/jsdelivr-wordpress-cdn-plugin/jsdelivr.php on line 224
