No log, no calendar file

have you tried if it works with https:// instead of https:// ?
additionally, you can use caldav2ics as a test/debugging tool.
just set $LogEnabled to true in the config section, as well as your server URL and credentials.
you can also fiddle with the curl options (see line 94 ff) in there.

The calendar.ics file contain only those information :
BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//hoernerfranzracing/caldav2ics.php
END:VCALENDAR
It’s look like there is an issue when reading the xml data the response from CURL
$xml = simplexml_load_string($response)
$data = $xml->xpath(‘//cal:calendar-data’);

I hope it’s help.

Ok, so your server actually does send calendar data ?? .
this, however, cannot be parsed correctly, as it seems.
can you send me the complete logfile by email to
expires190731 [AT] hoernerfranzracing.de ?
and the output of phpinfo() ?

As suggested in the answer above, it turned out to be an issue with the servers answer which could not be parsed using the plugin’s xml->xpath method.
solution was an alternative parsing scheme in the already mentioned caldav2ics.
this can be run automatically via cron job, thus resolving the problem for the OP of this thread.
I’m closing this now as resolved, though I did not (yet) port the mentioned solution to wp-caldav2ics.
maybe I’ll do this later on, but no guarantee ?? .
(I have switched from WP to Grav recently and focus my development efforts there.
I’ll keep wp-caldav2ics alive, however, at least until a major rewrite will be necessary due to WP API/Policy changes…)
