After a recent report of incompatability of my calendar plugin with MySQL 4.0 I have refactored the 4.1 and above only queries to be much more backwards compatable. If you previously had problems installing the calendar (strings of SQL errors at the top of every page) then you might like to try reinstalling it. You can grab your updated copy from my programming page
If you discover any more bugs please continue to report them. This plugin is actively supported and I will update any and all bugs or errors discovered.
Thanks to all who have already installed and started using my plugin and to those who have thanked me personally in e-mail and over MSN.
