owncloud after upgrade from 9.1.4 to 10.0.0 calender app is not accessible via web interface

[FKBOX]

calender app 1.4.2 is not accessible with any webbrowser. The data are still in the database (mysql) and accessible via thunderbird lightning or android app (calDAV sync adapter). It is not possible with ios calDAV to sync calendar. How can I access the calendar app via webinerface? Need that for changes of calenders of sharing calendars to other users.

mysql> use owncloud;
ALTER TABLE oc_dav_shares ADD publicuri VARCHAR(255) NOT NULL AFTER principaluri;
solved all my calender problems. I can add calenders an delete. Syncing wiht ios is working and with android. Thunderbird was anyway working, though I coundn't access the calenders via owncloud webpage.
