I am new in this so forgive me.
I just tried to install the "Who's Online Enhancement 2.0ec full package by Graphicore" contribution and I ended up with this 2 errors in admin and catalog.
Fatal error: Cannot redeclare tep_get_ip_address() (previously declared in /mounted-storage/home45c/sub001/sc17389-CZLB/www/catalog/admin/whos_online.php:22) in /mounted-storage/home45c/sub001/sc17389-CZLB/www/catalog/admin/includes/functions/general.php on line 1332

Does anyone know what I should do?
