title: APEX 5 get_blob does not work
body: <p>I am working on an Oracle APEX (<em>Oracle APEX 5.03.00.03 on Oracle 11.2.0.1.0</em>) project and want to add a BLOB download field in a classic report. When I try to implement the build-in BLOB function, I get the following error when I try to use the download functionality:</p>
  
  <blockquote>
    <p>The requested URL /apex/apex_util.get_blob was not found on this server </p>
  </blockquote>
  
  <p>When I simply display the ID of the table containing the BLOB, it seems to work fine.</p>
  
  <p>Can anyone suggest why I get this error message?</p>
  
  <p>Detailed error message:</p>
