a few days ago DAVx suddenly stopped to sync with my caldav remote Runbox calendar.
I upgraded to latest DAVx 2.4 but the error is still there.
I get a HTTP 500 Internal Server Error, the Interesting part seems to be here :
<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
<s:message>SQLSTATE: Integrity constraint violation: 1052 Column 'displayname' in field list is ambiguous</s:message>
Has something changed recently on DAVx side regarding this ?
Or if the problem is on server side what should I say to them ?
Thanks for your help !
