I use Google Calendar to sync my business appointments between my Macbook Pro, my iPhone 4 and my secretary's macbook. Everything always worked fine until last saturday. It still syncs without problems between the iphone and Google, and modifications progagates from the iphone to google to the macbook pro but it doesn't go backwards. The sync stops with the message "calendar has not been found on the server. Check the URL " (or something like that: the message is in italian, so be forgiving if this is not the correct traslation). I tried to delete the calendar and adding it back, but to no result. Everything works fine for the first sync and then brakes (blue triangle with an exclamation mark).
Everything works fine for my secretary's macbook.
Thanks in advance
MacOS 10.6.8. , Macbook pro 2GHz i7, iphone 4 iOS5.
I just tracked it down. With ical closed I went to /users/Your name/lybrary/calendars and removed "calendar cache" and "calendar cache~" then I restarted iCal. Everything seems fine now. I tried to make some new appointments and moving them, checking the sync through the browser. Everything worked perfectly.
