Using browser cache does not work

Question

The Google Pagespeed tool is displaying error:

Take advantage of browser cache.

My website: buscaempresas.com.br.

I activated the modules on my server expires and headers, then I added in htaccess the configuration below:

#Força a utilizar Cache-Control e Expires header
<IfModule mod_headers.c>
  Header unset ETag
</IfModule>
FileETag None
<IfModule mod_expires.c>
 ExpiresActive on
 ExpiresDefault "access plus 1 month"
 ExpiresByType text/cache-manifest "access plus 0 seconds"
 # Html

</IfModule>
#Força o IE a sempre carregar utilizando a última versão disponível
<IfModule mod_headers.c>
  Header set X-UA-Compatible "IE=Edge,chrome=1"
  <FilesMatch "\.(js|css|gif|png|jpeg|pdf|xml|oga|ogg|m4a|ogv|mp4|m4v|webm|svg|svgz|eot|ttf|otf|woff|ico|webp|appcache|manifest|htc|crx|oex|xpi|safariextz|vcf)$" >
    Header unset X-UA-Compatible
  </FilesMatch>
</IfModule>

Still the error keeps showing. I have tried several things but could not fix this error.

The resources that present the problem are external:

You have no control over them, as I said in this reply:

There’s no way to fix it, but it’s not a serious problem at all.

The other error message has nothing to do with caching, the problem is in rendering blocking:

Remove rendering lock Javascript:

It’s not just a copy+Paste, read and understand the proposals and apply as needed.
