title: Error Restarting Apache - "SSLCACertificateFile takes one argument"
body: <p>I am trying to set up SSL for my website. In my Apache website hosts file I am using:</p>
  
  <pre><code>SSLEngine On
  SSLCertificateFile /etc/ssl/localcerts/www.website.com.crt
  SSLCertificateKeyFile /etc/ssl/localcerts/www.website.com.key
  SSLVerifyClient require
  SSLVerifyDepth 1
  SSLCACertificateFile /etc/ssl/localcerts/ca-client.pem
  </code></pre>
  
  <p>I am getting this error message when restarting Apache:</p>
  
  <pre><code> * Restarting web server apache2                                                                                                          [fail]
   * The apache2 configtest failed.
  Output of config test was:
  AH00526: Syntax error on line 25 of /etc/apache2/sites-enabled/website.com.conf:
  SSLCACertificateFile takes one argument, SSL CA Certificate file ('/path/to/file' - PEM encoded)
  Action 'configtest' failed.
  The Apache error log may have more information.
  </code></pre>
  
  <p>If I comment out the SSLCACertifcateFile lines, the website works perfectly. As expected the SSL is "Not Trusted" without the CACertificate.</p>
  
  <p>How can I debug this to figure out why I can't include the SSLCACertificateFile? What does the error mean? </p>
