We installed NAV2015 CU3 on our database – and facing issue
with the web client.
Web client opens ok and runs some pages but then stops with error
"A server error has occurred, and the content cannot be displayed. Refresh
the page or open a new browser window"
Error message: Value cannot be null.
Event Viewer says:

Finally, the new feature called “Social
Listening” is causing the issue.
This new feature is introduced after
NAV2015 RTM and uses a Dll and some pages use the fact boxes related to “Social
Listening” and Dll which is required is missing in Database.
Solution:
1. Open Control Add-In’s page from RTC or Webclient
2. Add below line using New action (You can check Codeunit 2 Company-Initialize
function InsertClientAddIns to copy instead of typing)
3. Click Import and choose the path where Social Listening Dll is located.
Now Webclient is working fine J
