Rule can not be deleted

[David Diephuis]

When I try to delete a Rule an Unknown error occurs. 

The rule i try to delete is a rule about deleting and cloning issues. I try to prevent that issues are deleted by cloning the deleted issue to a back up project. Untill now this keeps failing becouse he could not create the issue in that project. 

But now the rule can not be deleted or deactivated any more

Hi David,

Not sure right off hand why it won't let you delete the rule, but first, why don't you just change the permission scheme to not allow users to Delete issues? Then you wouldn't need a rule.  :-)
