Resolving nextcloud webdav issues

NethServer Version: latest
Module: nextcloud
i get the error below
id like to resolve the following issues in my nextcloud instalaltion.

Hi

This MySQL error is only relevant if you’re using a 4Byte language like chinese, japanese or arabic…

You can safely ignore this otherwise.
I have about 20-30 NethServer with Nextcloud running, and no problems with this…

There is another post about this, and the devs elaborate on the issue (or non-issue!) and the background is explained - basically an upstream issue…

The other two problems can be solved in the new cockpit. Go to Apps, choose Nextcloud, go in there to settings and set the tick below…

My 2 cents

Regarding .well-known caldav/carddav, remember this note about webtop/SOGo:

Nextcloud — NethServer 7 Final
CalDAV and CardDAV
Some CalDAV and CardDAV clients may have problems finding the proper sync URL and need automatic service discovery. Service discovery is enabled by default if a custom virtual host for Nextcloud has been configured.

To enable the service discovery even if Nextcloud is running on the default URL, check the Enable CalDAV and CardDAV auto-discovery field.

Note
When enabling DAV auto-discovery, please make sure WebTop or SOGo are not already installed.

If the WebTop is installed which is the procedure ?

Thank you very muitch
