PHP error on general settings page when no CAPTCHA points defined

Hi @all,

when you submit the general CAPTCHA settings form with no challenges defined, you get the following error:

warning: Invalid argument supplied for foreach() in sites/all/modules/contributed/utils/captcha/captcha.admin.inc on line 145.

So I guess you should wrap the loop with an if-statement that checks if $form_state['values']['captcha_types'] is an array and not empty. You could use the attached patch to change the code as mentioned.

Thanx in advance & cheers
