I just started using pro forms. Created a simple form using steps. looks fine in the builder but when I view in the front end I receive several undefined array key “type” in the ProForms.php file. Not sure how to solve this.
You seem to have debug mode activated. Otherwise, such php notices and warnings would be hidden. So please set WP_DEBUG to false in your wp-config.php and everything should be fine.
Anyway, could you share the exact warnings here or via ticket? Cannot reproduce it locally
