I have opened a bug report for the port as shared_calendars is a FreeBSD package. The Apache configuration is copied from the working installation with the ip addresses altered to suit. What is the relationship between /usr/share/squirrelmail/plugins/calendar/setup.php and shared_calendars? [root@webmail-1 ~]# tail /usr/local/www/squirrelmail/plugins/calendar/setup.php /** * Adds Calendar link to upper menu * @return void */ function calendar() { displayInternalLink('plugins/calendar/calendar.php',_("Calendar"),'right'); echo " \n"; } ?> This is the shared_calendars setup.php just in case this is what you actually wanted: [root@webmail-1 ~]# tail /usr/local/www/squirrelmail/plugins/shared_calendars/setup.php { include_once(SM_PATH .
