3.  Tried the following, which did not resolve the issue for all of the Portlets on the Home menu:

  • In Clarity go to Home->General
  • Click the Personalize icon on the right hand side of the page
  • Click Restore Defaults.


This can happen if the user's current homepage is corrupted or no longer is valid.


All Supported Releases


Reset the user's homepage to the default:
1. As an Admin, go to Administration->Organization and Access->Resources 
2. Filter for the user with the issue, and click on the link to the user to access the Properties tab
