title: cPanel with PHP selector shows WordPress Error "PHP installation appears to be missing the MySQL extension which is required by WordPress"
body: <p>After an upgrade of MySQL to use MariaDB 10, multiple sites on my CloudLinux cPanel server are just white screens with <code>Error: Your PHP installation appears to be missing the MySQL extension which is required by WordPress</code> </p>
  
  <p>I can choose the PHP version per account, but selecting any from 5.3 up to 5.6 still doesn't work.</p>
  
  <p>Nothing is working, rebuilding Apache and PHP using <code>/scripts/easyapache/</code> is not working, and running <code>&lt;?php echo phpinfo(); ?&gt;</code> on the failing sites shows there is no <code>mysql</code> or <code>mysqli</code> extension.</p>
  
  <p>How can this be fixed?</p>
