There is an error in the adrotate-fonctions.php, some fields are not found line 305 on the request :
$ad = $wpdb->get_row($wpdb->prepare("SELECT id, bannercode, tracker, link, imagetype, image, cbudget, ibudget, crate, irate FROM ".$wpdb->prefix."adrotate WHERE id = %d;", $ad_id));
Easiest way found and working for me : replace the list of fields (not found like cbudget, ibudget & crate) per :
$ad = $wpdb->get_row($wpdb->prepare("SELECT * FROM ".$wpdb->prefix."adrotate WHERE id = %d;", $ad_id));
Easy :)
