I'm setting up wp-piwik in a multi-site environment. Everything seems to be set up correctly but the tracking code will not insert automatically. I've been seeing this error in the logs and I'm wondering if this is the cause:
PHP Notice: Undefined index: track_cdnurl in /var/www/.../public_html/content/plugins/wp-piwik/classes/WP_Piwik_Settings.php on line 109
Is there a fix for this error and could it be preventing the insertion of the tracking code?
