** I changed permission on calendar.pl to 744 **
I don't recall that being mentioned in the docs. Script files usually need to be chmod to 755 (read and execute - the important one) or 775 on some servers. Check your host's CGI FAQs for what is required on their server.
** calendarscript directory to 777 **
Many servers don't allow files or directories to be chmod to 777 for security reasons. Check your host's CGI FAQs for what is required on their server.
Generally speaking, data files and their directories shouldn't usually need permissions above 666 (766 if you're superstitious or your server's set up requires it, check your host's CGI FAQs).
