title: SugarCRM SOAP test call fails
body: <p>I am attempting to test a SugarCRM Soap connection using the following code:</p>
  
  <pre><code>&lt;?
  define('sugarEntry', TRUE);
  require_once('include/nusoap/nusoap.php');
  $sugarclient = new nusoapclient('http://www.mycrmurl.com/soap.php?wsdl',true);
  
  
  echo $sugarclient-&gt;call('test', 'test string');
  ?&gt;
  </code></pre>
  
  <p>Unfortunately, the test call returns NULL. Thoughts on how to begin troubleshooting?</p>
