Notifications only works when you set [AMS_DIR]/ in SEO setting
Otherwise it reffers to ttp://www.xoops.org/titleofarticle/notification_update.php which obviosely doesnt work. It s a probably path bug but i have no idea how to fix it.
The same problem with comments, i reported it to developer many months ago but we still didn t get any solution. I wish to migrate to news module if there was any script.
