I have a form that has been working great for months:
http://www.challengeblog.org/submit/
One of the text fields is set to "medium" length. When I try changing it to "long" and saving the edited form, everything looks okay -- until I try looking at it live on the site. Then I get three instances of this error:
Warning: Invalid argument supplied for foreach() in /home/kgagne/mschallengeblog/wp-content/plugins/gravityforms/form_display.php on line 746
Trying to edit the form shows the same screen as creating a new form, and loading the entries results in blank listings. The only way to restore my form and its data is to revert to a backup of my MySQL database.
I haven't tried editing my other forms to know if this is a consistent issue with using Gravity Forms 1.4.4 to edit a form that was made with an earlier version.
