Unable to configure CalDav server

[Ganneff]

Hi,

i installed following the INSTALL.md, but I am unable to get it to accept my caldav server. Log in errors.log is entirely not helping me see why:

Output in browser is a plain "Your information are incorrect or incomplete Could'n find a CalDAV-collection under the url".
Now, the url does work for other tools to access, so I don't fully believe this...

My server is a NextCloud (24.0.3), RoundCube is 1.6.0, PHP is 8.1.9.

URLs I tried are:
(Nextcloud lists as Primary): https://SERVER/remote.php/dav
(Nextcloud lists as MacOSX): https://SERVER/remote.php/dav/principals/users/joerg/

Any idea?

Greetings,

Hi,

It seems that the plugins isn't php 8 ready, we have to look at it, but it's only warning, it should not be the problem

This is the url we use
https://SERVER/remote.php/dav/calendars/USER/personal/

And also the version of roudcude 1.6 is not tested yet with this app, but after a quick check it should work, test needed

We've just update the app, could you try again ?
