CiviCRM Community Forums (archive)

I have installed Drupal 6.16 and CiviCRM 3.1 for a new website I am developing.  The host is a shared account on GoDaddy.com.  I have other Drupal sites there, but hadn't attempted to install Civi. 

The drupal is installed fine, everything looks normal.  When I log in as administrator and click on CRM, I get the following error

Fatal error: Class 'HTML_QuickForm_Controller' not found in /home/content/e/i/g/<myname>/html/<mydomain>/test/www/sites/all/modules/civicrm/CRM/Core/Controller.php on line 51

I opened up Controller.php, to see if there was anything obviously awry, but I do not know how to code php, and I didn't see anything obviously wrong with the logic.  This is a clean install, simply put of all of the files just as they were unzipped, nothing edited.  If anyone can point me in the direction of resolving this, I would very much appreciate.
