[Davical-general] Deleting calendar entries not working after server migration

[Musall, M. <li...@mu...>]

Hi,

I migrated an Ubuntu 12.04 LTS installation (with whatever Davical was current back then, can't look it up any more) to a new Ubuntu 16.04 LTS (Davical 1.1.4-1), and have residual problems with deleting calendar entries from iOS. On the server, I frequently see things like this in the apache error log:

davical: ***: ERROR:XML parsing error: Unknown (202) at line 3, column 33
davical: ***: ERROR:Error occurred in:\n<schedule-default-calendar-URL xmlns="urn:ietf:params:xml:ns:caldav">\n <DAV::href>/mmdavical/caldav.php/conny/connyOfficeCalendar/</DAV::href>\n</schedule-default-calendar-URL>\n
davical: ***: ERROR:XML namspace error but tags extracted, trying to continue

I did run the upgrade-davical-database script recently, although missed that in the beginning.

Based on the error messages, I was unable to find the cause, let alone fix it. PHP installation seems fine, the dependendies listed in setup.php are all green and "Passed".

Any hints?

Thanks
