"shared with you", "shared with others" and "shared by link" empty

[cubical23]

1. Login
2. goto "Files"
3. click "shared with you", "shared with others" or "shared by link"
4. nothing is shown

Expected behaviour

Files or Folders that have been shared should be visible

Actual behaviour

Nothing is shown (shared files do exist of course!), this happens since upgrading to 9.0.0

Server configuration

CentOS 7

Web server:
apache httpd 2.4

Database:
mariadb

ownCloud version: (see ownCloud admin page)
9.0.0

Updated from an older ownCloud or fresh install:
updated several times, last update was 8.1.1 to 8.2.3 to 9.0.0
I also run another instance of owncloud on another server, that's almost identical and which has also been updated with the same procedure, which is working as expected.

Login as admin user into your ownCloud and access
