Hi,
I have the same problem as flatspin (internal server error and so on) ; the upgrade from nextcloud 13 to nextcloud 14 broke it.
httpd and slapd are up, i use the latest Nethserver version. The other services installed on my server (mail, SOGo and so on) work fine.
The logs don’t give me a clue of what is happening : /var/lib/nethserver/nextcloud/nextcloud.log
It sounds like this bug report : Nextcloud 13 - Call for QA! but i can’t log in as administrator.
Any idea ? Thanks.
Stef
