The message tells you that the problem is the so called "executable owner" of the script. The "executable owner" is a mechanism to protect against Trojan horse attacks: a user with low priviledges creates an executable object that does bad things when executed by a user with high priviledges. The protection restricts the effective permissions to the intersection of the current user permissions and the executable owner permission. Probably, the executable owner of this script does not exist in your test instance (but it exists in the other instances). Use "take ownership" to change the executable owner (or create the executable owner). -- Dieter
