Radio buttons cause a critical error

Took me forever to figure this out today as it turned out gravity forms was messing up my site after I upgraded the plugin.

If I create a form made up of fields other than radio buttons - everything works. When I add radio buttons to the form I end up getting a critical error.

Any idea how to fix this?

Hi Daniel. I don’t have any other reports of this happening on Gravity Forms. I recommend opening a support ticket for the issue so we can figure out what the problem is:

Thank you.
