ONLYOFFICE ist in den Einstellungen sichtbar aber nicht in der Leiste + beim lokalen öffnen der Dateien leeres Dokument

Hallo,
ich habe seid einiger Zeit auf meiner Nextcloud (nc18) auf einem Ubuntu 18.04 Vm laufen,
außerdem habe ich ONLYOFFICE und den Document Server darauf laufen.
Nun mein Problem:
Ich habe Dateien in der Nextcloud gespeichert lassen sich aber nicht mehr öffnen und alle mein Backups sind wie das Original leer. Interessant ist aber, dass ich ONLYOFFICE noch in den Einstellungen sehe. Dazu : es lässt sich auch kein neues Dokument erstellen.
