Can't reproduce with Kronolith H5. The events are loaded fine without 
error and displayed correctly.

Hi Jan,

Di you find out anything about my problem?

Could you please send me the requests that horde aks for the caldav in 
order we could adapt our code? Or where can we find this?

Thank you very much in advanced.

Kind regards,
Héctor Moreno.

Hi Jan,

Please find attached the .ics exported from our CalDAV server.

There are 3 events on this calendar. One of them is the uploaded from 
kronolith.

Let me know if you need something else.

Thank you very much.

Kind regards,
Héctor Moreno.

So it's *not* working yet. And this gets me back to my first question: 
Get us the content of such a calendar.

Hello Jan,

The errors are those which I've shown the other day.

I don´t understand why it's possible to upload an event but not 
download another event (correctly set with its dates).

Thank you very much.

Kind regards,
Héctor Moreno.

So is there actually any error at all? Or just the messages in the 
logs, which are just warnings by the way.

Hi Jan,

At first I thought that the event didn't upload to the server because 
I was watching the logs and I saw the errors.

Sorry for the confusion.

Thank you,

Kind regards,
Héctor Moreno

You said in your first comment that you cannot subscribe to that 
calendar from Horde. So how do you add an event then?

Hi Jan,

Sorry for not answering that question, I forgot it because of all the logs...

If we create an event in that subscribed calendar from horde, it 
uploads to the server.

What do you think is the problem?

Thank you very much in advanced,

Kind regards,
Héctor Moreno.

You still didn't answer the only question that I asked.

Hi Jan,

According to your advice, we have removed all events and tried to sync 
again. But it is still impossible.

This first part of the log is when we add an empty calendar from the 
server to kronolith:

This is when we create an event on the server side and try to sync in 
kronolith:

line 317, referer: http://horde_server/kronolith/


And this is when we create an event on kronolith in the subscribed calendar:

May 22 12:28:11 carpe10 HORDE: [kronolith] The remote server at 
https://url_to_my_calendar_caldav doesn't support an WebDAV protocol 
version 3. [pid 18480 on line 612 of 
"/var/www/html/horde/kronolith/lib/Driver/Ical.php"]


If you need more info, please let me know.

Thank you very much in advanced.

Kind regards,
Héctor Moreno.

Looks like the calendar returns an event without a start time, which 
is required in almost all cases. Can you upload the content of such a 
calendar?

Hello everybody,

We have installed horde 4 with kronolith 3.0.16.
We have also installed another CalDAV server.

We wish to subscribe the CalDAV calendars from our server in 
Kronolith, but it is impossible. These are the logs:

It is possible to subscribe in Thunderbird using CalDAV, so our server 
works correctly.

Could you please give us a clue to solve this?

Thank you very much in advanced.
Kind regards,

Héctor Moreno
