Problems with encryption in 11.1

Update: Here is the full output from the nextcloud.log file:

{"reqId":"zBCt8E8UszYWNkynMgWY","remoteAddr":"X.X.X.X","app":"no app in context",
"message": "Encryption module \"\" not found, file will be stored unencrypted (Default 
encryption module not loaded)","level":2,"time":"2017-02-11T19:40:14+00:00","method"
:"GET","url":"\/ocs\/v2.php\/apps\/notifications\/api\/v2\/notifications","user":
"testuser","version":"11.0.1.2"}

x.x.x.x is my current home IP address where I am browsing from (not the server)
I also just added a federated cloud share with another test install of NC 11.1:

  • that share was notified in the browser (“New incoming share”)
  • I clicked “Accept”
  • then the spam of errors started hitting the log file
  • no share ever showed up, the “Shared with you” tab does nothing (not even a loading animation, just blank)

Both servers have home folder encryption enabled and working.
