Une erreur inconue est survenue

I run ubuntu 22.04
Nextcloud version 23.0.3
calendar, cardav and password
ovh mutualisé
PHP version 8.0
Mysql V5.6
The issue you are facing:
After migrating to nextcloud V 23.0.4, I could’nt see my calendars anymore : I get a blank page.
I switched back to nextcloud V 23.0.3 and it was possible to see my calendars.
Unfortunately, after days the calendars disapeer from webdav, but was still working OK since I had 2 thunderbird and 2 phone android sync’ed.
Since a few days, I get the error “unknown error happened” while I upload any file and today, trying to see the users defined or applications, I got a blank page.

I get no error in the /nextcloud-data/log at no step of described problem. Here is my config.php :slight_smile:

  • <?php
  • $CONFIG = array (
  • ‘instanceid’ => ‘xxxxxx’,
  • ‘passwordsalt’ => ‘xxxxxx’,
  • ‘secret’ => ‘xxxxx’,
  • ‘trusted_domains’ =>
  • array (
  • 0 => ‘plusjamaisca.ovh’,
  • ),
  • ‘datadirectory’ => ‘/home/undnhxl/www/nextcloud-data’,
  • ‘dbtype’ => ‘mysql’,
  • ‘version’ => ‘23.0.3.2’,
  • ‘overwrite.cli.url’ => ‘https://plusjamaisca.ovh’,
  • ‘dbname’ => ‘xxxxxx’,
  • ‘dbhost’ => ‘xxxxxx’,
  • ‘dbport’ => ‘’,
  • ‘dbtableprefix’ => ‘xxx’,
  • ‘dbuser’ => ‘xxxxxx’,
  • ‘dbpassword’ => ‘xxxxxx’,
  • ‘installed’ => true,
  • );

Is there any solution other than re-install the whole ?
