Custom properties are not saving on additional websites

Updated January 3, 2017


This article discusses the issue with custom properties that are not saving on additional websites. There are no errors shown in the information service.



NPM 11.5.3



This is due to duplicate websites in the websites table.



  1. Clean up the websites table so that there is only the website(s) in this table that are actually being used.
  2. Run the following queries:

Delete from pendingnotifications

Delete from subscriptions

Delete from subscriptiontags

    3. Restart information service v3 on all pollers/websites.
