I am trying to make a form where the visitor can update a front end form [mb_frontend_form id="dc-ticket" edit="true" submit_button="Update" ajax="true"] and im passing in the post ID via url params ?rwmb_frontend_field_post_id=110 but I receive the message 'You are not allowed to edit this post'. Is there a way around allowing the visitor to edit a post when not signed in (guest/visitor)?
