there was no previous installation as this is a fresh install.

Also, as stated previously. The responsive_classic template in use already includes the $zco_notifier->notify('NOTIFY_FOOTER_END', $current_page); mentioned in the installation_readme.txt file. It does not populate the user_tracking db table, but calling the function zen_update_user_tracking(); works as it always has.
And with the includes/auto_loaders/config.user_tracking.php and includes/classes/observers/class.user_tracking.php in place as well as all of the version scripts being run: please identify what files are located in admin/includes/installers/user_tracking/
With all of that entered/applied, then all of the database settings would exist to allow the plugin to function. Otherwise there are settings that are missing that could cause the issues you are describing.
