Hi,
1) Make backup of je KSubscribers database.
2) Could you please follow the below steps:
* look for <Drive>:\Kaseya\DBInstall\AgentProcedures\script\loadSubAgentProcs.sql in your kaseya server
* Open file in SQL management Studio - check that you have the "ksubscribers" database selected - click execute
This will create a job in the database that will re-load the kaseya sub procedures.
As Always this is at your own risk :)
Had the same issue. This was i got from kaseya support. And fix it with me.
Hope it will help you.
