A date of 1/1/9999 looks very much like anuninitialized field.I suggest you save your existing *.ics file(s) somewhere as a backup,delete or rename the calendar from within Evolution, then create anentirely new calendar (also in Evolution), and import the backup .icsfile(s). That should at least start things off in a consistent state.poc I have backed up my calendar.ics file - looking at it with notepad it looks ok no corruption and the edits I made to appointments today are all there. I can't delete my calendar file as the command is greyed out. The delete contacts command is also greyed out. Not sure why. However I have found that Under Evolution Accounts - Address Book Properties - Type on this computer - Name Personal there is a tick box 'use in Birthdays & Anniversaries Calendar' if I untick this I am now able to create new appointments instead of getting the error message above. Does this help in the diagnostics ? I can use that as a temporary fix but it would be good to get Birthdays & anniversaries shown again. Could the error message be the result of a corrupted / invalid birthday in the address book as I have edited several of these recently ? Thanks John Murrell |
