title: How to set post_max_size on apache server with htaccess (getting internal server error)
body: <p>I am trying to increase the maximum post size limit on my server.</p>
  
  <p>Here is the .htaccess file:</p>
  
  <pre><code>php_value upload_max_filesize 20M
  php_value post_max_size 20M
  php_value max_execution_time 200
  php_value max_input_time 200
  </code></pre>
  
  <p>However it does not seem to work and throws a 500 Internal server error.</p>
  
  <p>Any ideas why this could be happening and how to overcome this?</p>
