Hello,
The new image contains fixes for ExtendedSearch. It seems your situation requires manual operations.
Could you please run the following commands:
($your_container_name) should be replaced with your BlueSpice container name.
In your Univention server:
docker exec $your_container_name /usr/bin/php /var/www/bluespice/extensions/BlueSpiceExtendedSearch/maintenance/initBackends.php --quick
docker exec $your_container_name /usr/bin/php /var/www/bluespice/extensions/BlueSpiceExtendedSearch/maintenance/rebuildIndex.php --quick
finally
docker exec $your_container_name /usr/bin/php /var/www/bluespice/maintenance/runJobs.php
These steps will recreate Extended Search index.
Regards,
Gokhan
