I have the following code in my .htaccess file to leverage browser caching (and gzip), however when I run tools such as Google Page speed or Gtmetrix I still am getting the error tha my website is not using leverage browser caching. Link to my website

.htaccess code:

 <FilesMatch "\.(ico|jpg|jpeg|png|gif|js|css|swf|pdf|flv|mp3)$">
<IfModule mod_expires.c>
 ExpiresActive on
 ExpiresDefault "access plus 14 days"
 Header set Cache-Control "public"

  # My favicon
ExpiresByType image/x-icon "access plus 1 year”

# Images
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"

# CSS
ExpiresByType text/css "access 1 month”

# Javascript
ExpiresByType application/javascript "access plus 1 year"

</IfModule>
</FilesMatch>
<FilesMatch "\.(html|htm|xml|txt|xsl)$">
 Header set Cache-Control "max-age=7200, must-revalidate"
</FilesMatch>

 </IfModule>

I too had the same problem, this worked for me......,

    Not sure if this will help you or not, but I got it and added it to my .htaccess file. 

Worked like a charm.
