Warning: Invalid argument supplied for foreach()... [#2369799]

Hi,

Upon finalizing the quiz and viewing the results of the quiz (the last screen of a quiz) I got the following error:
"Warning: Invalid argument supplied for foreach() in element_children() (line 6428 of /home/xxxxx/public_html/includes/common.inc)."

The above warning line was repeated around 15-20 times...

Thanks for looking at it

We're also seeing this problem. When the user clicks on "Finish" it goes to frontpage and gives the following errors:

Warning: Invalid argument supplied for foreach() in element_children() (line 6540 of /usr/www/users/foldername/includes/common.inc).
Warning: array_keys() expects parameter 1 to be array, object given in views_bulk_operations_argument_selector_action() (line 32 of /usr/www/users/foldername/sites/all/modules/views_bulk_operations/actions/argument_selector.action.inc).
Warning: implode(): Invalid arguments passed in views_bulk_operations_argument_selector_action() (line 32 of /usr/www/users/foldername/sites/all/modules/views_bulk_operations/actions/argument_selector.action.inc).

I appreciate any help ;)
