Hi There, DAViCal 1.1.1 running, with several client types. Installed and got running CalDAVZap today. Browser is Firefox 21.0 on Linux Mint 13, using the Mate desktop. When I try to create an event in my calendar, I get "Error: 'unable to save the event': unauthorized!" Error Console tells me: Timestamp: 05/17/2013 04:54:35 PM Error: [Exception... "'Method not implemented' when calling method: [nsIAuthPrompt2::asyncPromptAuth]" nsresult: "0x80004001 (NS_ERROR_NOT_IMPLEMENTED)" location: "native frame :: <unknown filename> :: <TOP_LEVEL> :: line 0" data: no] Thanks, Jim -- Note: My mail server employs *very* aggressive anti-spam filtering.
