RED MESSAGE in /settings/admin/overview:

Your web server is not yet properly configured for file synchronization because the WebDAV interface seems not to work. (translated for french)

Nextcloud version (eg, 20.0.5): 23.0.3
Operating system and version (eg, Ubuntu 20.04): Linux 4.9.0-0.bpo.12-amd64 x86_64 (Infomaniak Shared hosting)
Apache or nginx version (eg, Apache 2.4.25): 2.4.51
PHP version (eg, 7.4): PHP 8.0.17

The issue you are facing:

Hi. I upgraded a few days ago (it seems) to version 23.0.3. This morning I noticed that I had no sync with my calendar. I go to the admin, and I have this:
“Your web server is not yet properly configured for file synchronization because the WebDAV interface seems not to work.”.
What should I do?

(ThanksI can read MP3 for my Android too.)

Is this the first time you’ve seen this error? (Y/N): Y

ERREUR MESSAGES :

Il y a quelques erreurs concernant votre configuration.

    Votre serveur web n'est pas encore correctement configuré pour la synchronisation de fichiers parce que l'interface WebDAV semble ne pas fonctionner.

    Pas de mémoire cache configurée. Pour améliorer les performances, merci de configurer un memcache, si disponible. Des informations sont disponibles dans la documentation ↗.
    Le module PHP OPcache n'est pas correctement configuré. Veuillez regarder la documentation ↗ pour plus d'informations.
        The OPcache buffer is nearly full. To assure that all scripts can be hold in cache, it is recommended to apply opcache.memory_consumption to your PHP configuration with a value higher than 128.
        The OPcache interned strings buffer is nearly full. To assure that repeating strings can be effectively cached, it is recommended to apply opcache.interned_strings_buffer to your PHP configuration with a value higher than 8.
