Hello everyone,

If you're trying to use CalDavZAP on the (web) client side, and radicale on the server side, you might have encountered a 404 error on CalDavZAP web console.

I've been stuck on this problem an entire evening and I finally found the error.

Don't forget to enable CORS (cross-origin resource sharing : http://en.wikipedia.org/wiki/Cross-origin_resource_sharing ) on the radicale configuration so that CalDavZAP can access the radicale resources even if they are not available on the same domain.

This is simply done by adding the following configuration at the end of the radicale configuration file :

extract from /etc/radicale/config :

[...] # Additional HTTP headers [headers] Access-Control-Allow-Origin = * Access-Control-Allow-Methods = GET, POST, OPTIONS, PROPFIND, PROPPATCH, REPORT, PUT, MOVE, DELETE, LOCK, UNLOCK, HEAD, MKCALENDAR, MKCOL Access-Control-Allow-Headers = User-Agent, Authorization, Content-type, Depth, If-match, If-None-Match, Lock-Token, Timeout, Destination, Overwrite, X-client, X-Requested-With Access-Control-Expose-Headers = Etag [...]

You can also restrict "*" to a more resrtictive list of domains.

Hope this helps...
