just reposting what Panos Karampis wrote in this this thread. that post was the solution for my case.

"The problem comes the new collaborative script which surprise surprise is running at your port 8091 by default. So, open the port in the firewall and go to Admin -> Left panel down is the Collaborative Editing -> restart the synchrony."

Hi Evan,

Try;

1. Disable 1 by one any user installed add-ons to see if one them is causing an issue 
2. Try a re-index
3. Try rebuilding the indexes:  https://confluence.atlassian.com/confkb/how-to-rebuild-the-content-indexes-from-scratch-on-confluence-server-110035351.html
