Problem: Portal is blank by an Error or Mistake

Problem

Your portal site is empty caused by an error or mistake.

Environment

UCS: 4.4-8

Solution

Please try to remove or delete:

mv /var/cache/univention-portal/`**portal.json** `/root/portal.jso_bak

restart your Portalserver:

kill -HUP $(ps aux | grep '[u]nivention-portal-server' | awk '{print $2 }')

you might check if the portal.json was recreated:

ls -latr /var/cache/univention-portal/

or go straight ahead to your site.



If there is a groups,json in your /var/cache/univention-portal/ and your portal ist still not working, keep this bug in mind.

Do the following steps with the attached python-File :
rebuild-portal-groups.py (1.2 KB)

root@kochmaa:~# systemctl stop univention-directory-listener
root@kochmaa:~#./rebuild-portal-groups > groups.json

—> Please Check the file groups.json :wink:

root@kochmaa:~# chgrp nogroup groups.json
root@kochmaa:~# mv groups.json /var/cache/univention-portal/groups.json
root@kochmaa:~# systemctl start univention-directory-listener

Delete:
/root/portal.jso_bak
