title: Netbeans autocomplete stopped working?
body: <p>I'm using Netbeans 6.9.1, everything was just fine however suddenly, it has stopped detecting any changes made to the code, e.g new variables, functions, etc. If I try to refactor/rename a variable, e.g by pressing CTRL + R, it says 'Refactoring not available in this context'.</p>
  
  <p>Its in a PHP project if that matters.</p>
  
  <p>Any ideas?</p>
