title: AddType in htaccess causes page to download
body: <p>I have read about 10 questions like this, but there seems to be no answer to this simple question.</p>
  
  <p>What could cause .htm files to be downloading instead of executed as php?</p>
  
  <p>I am using the following code:</p>
  
  <pre><code>AddType application/x-httpd-php htm
  </code></pre>
  
  <p>I have tried many combinations but no success.</p>
  
  <p>What else can I try?</p>
  
  <p>All I need is .htm and .html files to execute php.</p>
