what other files or formats do you use in your calendar account?

It’s a new calendar, I don’t have nothing special in it.

In my Baikal calendar, I see that “todos” is activate. Maybe I should disable.

The “notes” option is disable.

I don’t understand if I should use public link for this calendar to be open in open web calendar.

Hello,

I only want to see the calendar in a web page, without any additionnals fonctionality.

I don’t know what the difference between ics and caldav and witch is better.

I’m not sure that baikal can produce ics calendar.

Has someone already use Baikal with Open Web Calendar ? I wonder if it’s possible.

If there are other solutions, I’m interested.

Thank’s !

I also struggle to get any caldav calendar into the open web calendar. Didn’t succeed so far.

firefox console has status code 200 for the GET method. but the XML parser fails with
XML Parsing Error: syntax error

although it gets correct amount of calendar entries

then followed by:
Error: HTTP error! status: 500

Eventually, you could export your caldav calendar from thunderbird, as ics and then try to import to open web calendar via some url, although this is definitely not how we want it to work :grin:
