title: SSLCertificateChainFile is obsolete
body: <p>I'm on Apache 2.4.12, so <a href="https://httpd.apache.org/docs/2.4/mod/mod_ssl.html#sslcertificatechainfile" rel="noreferrer">SSLCertificateChainFile</a> is now obsolete, and any intermediate certificates are supposed to be included in the server certificate file. I cannot figure out how to do this, however--any combination of certificates other than <em>only</em> the site certificate inside the specified file causes an invalid key error. How do I properly include the intermediate certificate inside the file that I specify using <a href="https://httpd.apache.org/docs/2.4/mod/mod_ssl.html#sslcertificatefile" rel="noreferrer">SSLCertificateFile</a>?</p>
