I just discovered that my user Quest no longer have access to the Admin calendar, which it has had for over 5 years. All of a sudden they can't access it!!!
When they login "Access other users Calendar" is also missing.
How do I give Guest access to Admin's calendar???
Did something change recently? Check the WebCalendar FAQ for how to add a new admin account:
If you already have an 'admin' user then use 'admin2' or something else different in the SQL command.
