Invalid argument supplied for foreach() in image_fupload_imagefield.module on line 506

can you please elaborate on your fix? I'm new at this and I'm having the same issue.

Can't reproduce this error message. Perhaps you added some fields and didn't resave ImageFields settings page.

Hi,
get the same error,
really not expert, I'm sorry
but I cannot understand the solution,

"Solution add is_array check before foreach loop."

I get this error below, just after a fresh installation.

Fatal error: Call to undefined function image_node_type_load() in .../modules/image_fupload/image_fupload_imagefield/image_fupload_imagefield.module on line 60

Can someone explain me how work the solution proposed above?

I encountered this same error:

warning: Invalid argument supplied for foreach() in /var/www/html/drupal/sites/all/modules/image_fupload/image_fupload_imagefield/image_fupload_imagefield.module on line 506.

I had one image field using the FUpload widget, then I went and edit content type and change the name and id. That's it. Seems under some condition like this, form_fields_destroy() is called with $fields_to_remove == NULL?
