title: How to turn on magento error messages?
body: <p>I have installed Magento Community edition and tried creating my first simple hello world module. After a few hours I finally got it working.</p>
  
  <p>My issues were I had used incorrect casing in some of the XML tags.</p>
  
  <p>While trying to get it to work I tried to load the page a not found message was displayed, but no error.</p>
  
  <p>I have switched errors on in the admin control panel <code>System &gt; Configuration &gt; Developer &gt; Log Settings</code> and wrote a line which I know should have thrown an error but I just got a blank screen</p>
  
  <ol>
  <li>How do I get errors to display in Magento?</li>
  <li>Is it considered an error when I use incorrect casing in an xml file or is that an issue where I would not receive an error message? And if that is the case how would I quickly find the file that is causing the issue (obviously not a problem at the moment, but I can imagine as the module become functional it will be hard to find a single casing issue that is causing the problem)</li>
