1. I did a copy and paste of the code and placed it at the top of my .htaccess file and I am still receiving a 500 error.

2. Hello,

    

   Should the code be pasted exactly as stated above: 

    

   <pre class=”code_block” style=”width: 496px; margin: -10px 0px -30px 0px; line-height: .9em”>&lt;IfModule mod_deflate.c&gt;
   AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
   &lt;/IfModule&gt;&lt;/pre&gt;</pre>

    

   I put that exact code in my .htacess file and got a 500 error on my site.

   1. Hello Eboni,

      Here is a corrected version of the .htaccess rule provided by Jacob:

      <IfModule mod_deflate.c>
      AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
      </IfModule></pre>

      Thank you,

4. Thanks for that link Arn, I’ve tried what they say there but, it still won’t work. I supose there’s something on the apache configuration that should be tweaked, but being a shared hosting I don’t have access to it.

   1. Hello Danigar,

      Thank you for contacting us. This setting should work on our servers, but I was unable to locate an account with us to confirm.

      You can check that gzip is enabled by looking in your phpinfo page.

      Thank you,

5. I did this but only HTML files are compressed. Doesn’t work for .css or .js files.

   1. Hello Danigar,

      Sorry for the problem with Gzip. Try adding the following code under your the “AddOutputFilterByType” lines:

      
      Header set Content-Encoding x-deflate
      # Header set Content-Encoding compress
      # Header set Content-Encoding x-gzip
      

      You can find this solution discussed here. They discuss several alternatives if this option does not work.

      Hope that helps to resolve your problem!

      Regards,
      Arnel C.

   1. Hello ramesh

      How are you testing to see if the Gzip compression has been successfully enabled? As mentioned in our an introduction to Gzip and mod_deflate guide you can use this site:

      https://www.whatsmyip.org/http-compression-test/

      As also mentioned in that guide you can also enable Gzip compress in your .htaccess file with this:

      <IfModule mod_deflate.c>
      AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
      </IfModule></pre>

      Please let us know if that works for you.

      – Jacob
