Extension talk:Google Analytics Integration/Archive

I installed this extension on my MW 1.11(Alpha). Got Following error. (Note I have removed my hosting a/c name and put XXXXX instead for obvious reason.)

MediaWiki internal error. Original exception: exception 'MWException' with message 'Detected bug in an extension! Hook googleAnalyticsHook failed to return a value; should return true to continue hook processing or false to abort.' in /home/XXXXX/public_html/wiki/includes/Hooks.php:133 Stack trace: Exception caught inside exception handler: exception 'MWException' with message 'Detected bug in an extension!
