warning: Invalid argument supplied for foreach() in (...) \conditional_fields.module on line 466

I use this module for a content type. It works Excellent.
But I created another content type, and for each field I create or edit of this new content type, I have the following error:

warning: Invalid argument supplied for foreach() in C:\wamp\www\drupal6\sites\all\modules\conditional_fields\conditional_fields.module on line 466.

I'm using Drupal 6.8 with ConditionalFields 6.x-1.x-dev and cck 6.x-2.1 modules
