Tech note FS1417
The webmaster email address shown in error messages is incomplete or incorrect.
When FlashStats encounters most error conditions, it will display a web page explaining what the problem is and suggesting several fixes. This page may contain the email address of the webmaster in the form of a clickable mailto: link.
FlashStats uses whatever value is provided in the SERVER_ADMIN field provided by CGI. Therefore, if the email address is incomplete or incorrect then it's because something is misconfigured on your web server.
For Apache web servers, edit your http.conf file. Look for the line that contains the ServerAdmin directive.
For O'Reilly WebSite, open the server properties dialog box. On the first tab ("General"), edit the Admin Addr field.
For other web servers, consult your documentation.
