title: How to configure Codeigniter to report all errors?
body: <p>I had a line - <code>$autoload['libraries'] = array('database');</code>, in CI's <code>autoload.php</code>. Because of this I was getting a blank page. When I removed the <code>'database'</code>, option then I started getting the output.</p>
  
  <p>Now my question is not how to configure the database, but how to configure CI to speak its mind. When <code>'database'</code> was enabled all I got was a complete blank page. No error in php log, no error in Apache log, no error in CI log. In PHP I have set <code>E_ALL</code>. In my CI config I have set <code>log_threshold</code> to <code>4</code>, i.e. all messages should be logged. What more do I need to do?</p>
