Hi,
I have just tried adding a list custom field and saving the form but it came up with an error saying something like "There was an error when saving your form, please contact the support team ". The same happened for when i selected the option for my first image upload to be set as the featured image. I used your meta recovery tool but this did not fix the problem. Perhaps I have installed the beta version incorrectly? Do I need to uninstall all of the addons, and can I just whip the old GF folder off of my server via ftp and dump the new folder in, or do you suggest a different installation method?
