zendz found some problem regarding to Hall of Fame module. Its menu at the top of all pages has disappeared. I tried to directly access https://howforge.com/hof. The error message was "access denied". Fortunately, I found a patch at http://drupal.org/node/53875. Thanks chrisd and Steven for the patch of External URL support for menus broken by SA-2006-001.

Update: upload.module has been fixed for below error message.

warning: Invalid argument supplied for foreach() in .../modules/upload.module on line 432.
