Server Side Include and .htaccess file
If SSI's (server side includes) are not parsing properly try adding these lines of text within your .htaccess file:
If your filenames end in .shtml:
AddType text/html .shtml
AddHandler server-parsed .shtml
Options Indexes FollowSymLinks Includes
If your filenames end in simply .htm or .html:
AddHandler server-parsed .html
AddHandler server-parsed .htm
The older examples below, previously used to parse SSI, may not work with the latest version of Apache web server.
Remove these lines if they exist within your .htaccess file:
AddHandler text/x-server-parsed-html html
AddType text/x-server-parsed-html .html
Where is my .htaccess file?
Your .htaccess file is a text file found within your public_html directory.
