dmoore The script is looking for a mysql column that doesn't exist. It looks like you upgraded the Machform installation past v13.1 at some stage but forgot to run upgrade.php, which would have created the required column on all your form tables.
It is important that once you've upgraded your Machform files that you run upgrade.php, as per the instructions. You will hopefully find that doing this now will fix the problem. Otherwise you can contact support.
As a note to @yuniar, it might be an idea to force redirect the admin to upgrade.php if
NEW_MACHFORM_VERSION in upgrade.php is newer than the machform_version in the ap_settings table; this would avoid the problem of anyone upgrading files but forgetting to run the upgrade script.
