Problem Enabling Browser Caching

Both Google Pagespeed Insights and GTMetrix are telling me my Wordpress site does not have browser caching enabled. I added the following to the .htaccess file in public_html and it makes no difference! Header set Cache-Control "max-age=84600, public" ExpiresActive On ExpiresByType image/jpg "access 1 year" ExpiresByType image/jpeg "access 1 year" ExpiresByType image/gif "access 1 year" ExpiresByType image/png "access 1 year" ExpiresByType text/css "access 1 month" ExpiresByType application/pdf "access 1 month" ExpiresByType application/javascript "access 1 month" ExpiresByType application/x-javascript "access 1 month" ExpiresByType application/x-shockwave-flash "access 1 month" ExpiresByType image/x-icon "access 1 year" ExpiresDefault "access 2 days" Is there a common WHM/Cpanel issue that could be preventing the caching from being enabled?

  Do you have any caching plugin installed with your wordpress installation ? plugins like W3Total Cache can fulfill your requirements.

  Hello, Can you reproduce the same test results with a test page that's not part of your WordPress installation? If not, then you may want to look into WordPress plugins that utilize browser caching. Thank you.

  As noted above, you may have some other issues, but if you get to the point of implementing browser-caching, and want to do it globally for all accounts on your server, I have had good luck with adding the following to WHM -> Service Configuration -> Apache Configuration -> Include Editor -> Pre VirtualHost Include -> All Versions:
  ## Cache-Control # 1 YEAR Header set Cache-Control "max-age=29030400, public"
  Note that the above doesn't cache *.js, *.css, and *.php files, which may change frequently as sites are developed. While you're in there, you might also want to enable Gzip compression:
  # Enable GZIP Compression. SetOutputFilter DEFLATE # Netscape 4.x has some problems... BrowserMatch ^Mozilla/4 gzip-only-text/html # Netscape 4.06-4.08 have some more problems BrowserMatch ^Mozilla/4\.0[678] no-gzip # MSIE masquerades as Netscape, but it is fine # BrowserMatch \bMSIE !no-gzip !gzip-only-text/html # NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48 # the above regex won't work. You can use the following # workaround to get the desired effect: BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html # Don't compress images SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary # Make sure proxies don't deliver the wrong content Header append Vary User-Agent env=!dont-vary
  and also tweak your security:
  # This setup will give you a "B" on observatory.mozilla.org. To do better, you need to add "Header set Content-Security-Policy", which WP Super Cache breaks. # Block site from being framed Header always append X-Frame-Options SAMEORIGIN # Block pages from loading when they detect reflected XSS attacks in older browsers. Header set X-XSS-Protection "1; mode=block"
