The default for your VDS does not include the .shtml MIME-type. In order for your site(s) to work with .shtml files, you must do the following.

1. Login via SSH to your site
2. Type the command:

   cd /www/conf
   

3. Edit the file named "mime.types"
4. Between the lines that state:

   text/vnd.wap.wmlscript
   text/x-setext                   etx
   

   Place the line:

   text/x-server-parsed-html       shtml
   

   So that it looks like this:

   text/vnd.wap.wmlscript
   text/x-server-parsed-html       shtml
   text/x-setext                   etx
   

5. Save the file
6. Restart the Web Server:

   /www/bin/apachectl restart
