title: XDebug installed but not working
body: <p>I have just downloaded the latest xdebug for my windows machine running wamp and php 5.3.  After following the install instruction and restarting my services, it appears to be installed according to php info:</p>
  
  <p>xdebug</p>
  
  <p>xdebug support => enabled
  Version => 2.1.0</p>
  
  <p>However, if I try to use the following in a script:
  xdebug_start_trace('c:\test.txt');</p>
  
  <p>I get this error:
  Fatal error: Call to undefined function xdebug_start_trace() i</p>
  
  <p>What is going on?</p>
  
  <p>Thanks,
  Jonah</p>
