MikeyPNJ on "[Plugin: WP Super Cache] Installation went fine, but google still says need to leverage cacheing"

I installed this plugin as Google is telling me i need to leverage browser caching.
I installed the plugin, set it up, but there is ZERO change. It seems like its still not cacheing.
I then went and looked at the support and noticed the htaccess file in wp-content/cache didn't have "# BEGIN supercache <IfModule mod_mime.c> <FilesMatch "\.html\.gz$"> ForceType text/html FileETag None </FilesMatch> AddEncoding gzip .gz AddType text/html .gz </IfModule> <IfModule mod_deflate.c> SetEnvIfNoCase Request_URI \.gz$ no-gzip </IfModule> <IfModule mod_headers.c> Header set Cache-Control 'max-age=3, must-revalidate' </IfModule> <IfModule mod_expires.c> ExpiresActive On ExpiresByType text/html A3 </IfModule> # END super cache" like it said it should, so i deleted the info in there and added it.
Still not working.

please advise.
