Unable to access author URLs which have "cf#" in it
When trying to access any author URL with content finder ("cf#") in the URL, blank pages are loading and below exception is occurring:
20.07.2016 09:17:43.788 *ERROR* [10.19.9.39 [1469006263777] GET /cf HTTP/1.1] com.adobe.cq.sightly.WCMUse Failed to activate Use class
java.lang.NullPointerException: null
Does anyone have a clue what might be the issue. We have same code in a different server which works fine.
