Today while using Audience settings in navigation , I got the error while validating groups in Audience setting, even groups are correctly set.
The following error message was appearing during audience validation:
This entry cannot be validated. Exception Object reference not set to an instance of object. occurred
After some quick search on internet i found that, there might be possibility of User Profile Service is not associated with web application.
To check that, I went to Central Administration --> Application Management --> Manage Web application.
Selected my web application and clicked on "Services Connection"
The check-box in front of User Profile Service Application was unchecked. I selected the check-box and clicked OK.
Then I went to set the audience and problem was resolved.
Cheers!!!!!!. Hope this helps.
