[SOLVED] Multiple delete of activities (without real work)

Hi,
I want to do multiple delete of activities which do not contain real work. The issue is that as soon as the activity has an assignment, the mulitple delete can't succeed because I get the following message :
"#315 :
This action requires confirmation
Following dependent items will also be deleted
- Assignment (1)"

Is there a way to prevent the confirmation request so that multiple delete can be achieved in this case ?

Regards.

yes I saw that in another topic, I'm logged as admin and I changed the Specific update rights "can force delete" to yes (I saved and even logout/login afterwards)


but still I can't do multiple delete as you can see below




Is there another configuration that I missed somewhere ?

Regards.
