Hello, I am running Evolution 3.28.5-0ubuntu0.18.04.1 under Linux Mint 9.3 Mate 64 Bit Evolution has been operating satisfactorily since I installed it in February until the last couple of days when I get the error 'Failed to open calendar “Contacts : Birthdays & Anniversaries” Invalid object' when I try to create a new entry in the calendar. There is one previous post in the archive that implies that turning the calendars off and on again cures it - I have tried this but it does not work in my case. I have looked at the dta file in /home/john/.local/share/evolution/calendar/system and the only file is 'calendar.ics' which Has Read - Wrirte permission for th eowner and read only for the others. Changing the group to read write does not cure it. Nothing on the internet for this error other than the one report in the archive as shown above. The 'Birthdays & Anniversarys still show in the calendar and can be turned on & off with the tick box so evolution still seems to be reading the data. The error occurs even if I turn off B&A and then try to create a new appointment. Can anyone help me on fixing this. Thanks John Murrell |
