Cannot send Submit Notification Except from myself

Hi,I just copy my workflow.nsf from my computer to server…

All ACL already maintained…This .nsf already design to Submit email to the approver if user submit a request…

In the past it could be function…but now only myself as the requestor can send email to myself ! Another user can submit a request, and mark the request as “solved”, in short, they can also change status of the request…but they cannot send email notification…just myself can do it…Is there any steps I forgot when copy this .nsf to the server ?

thanks a lot
