Hi,
There are two things you can do in order to find the source of the problem:
1. Check that your cron task is working by following this documentation:
www.hikashop.com/support/documentation/5...cron-task.html#check
2. Check that your mass action is working by using the "process" button at the top of the mass action to manually trigger it.
You can remove filters, to see if it comes from a filter, or use an action "display the results" to see a listing of the results found with your filters, etc.
If both your cron task and your mass action work, then I don't see why you would have that problem.
