Body: <p>I am interested in using CiviRules to automate some processes within CiviCRM.  I am using CiviCRM 4.6.6 and installed CiviRules 2.4.  When I went to add a rule clicking Next from the first CiviRules Add Rule page I am directed to a page displaying "This page isn't working  <em>mysite</em> is currently unable to handle this request.  HTTP ERROR 500".  I receive the same error page when I attempt to "cleanup the cache" and any other process I have tested.  Everything returns to normal after I uninstall CiviRules.  Anyone know how I can fix this?  All help is appreciated.</p>

  I am interested in using CiviRules to automate some processes within CiviCRM. I am using CiviCRM 4.6.6 and installed CiviRules 2.4. When I went to add a rule clicking Next from the first CiviRules Add Rule page I am directed to a page displaying "This page isn't working *mysite* is currently unable to handle this request. HTTP ERROR 500". I receive the same error page when I attempt to "cleanup the cache" and any other process I have tested. Everything returns to normal after I uninstall CiviRules. Anyone know how I can fix this? All help is appreciated.
