Our site utilizes the Partial Entries add-on for one specific form. But even if the add-on is disabled on our other forms, the wrong embed URL is still returning (wp-admin/admin-ajax.php). I found that answer here. Is there a workaround for this? Or if we have the add-on enabled, all of our forms will return this URL?
You could add a hidden field to the form with the default value set to {embed_url}. The field will be populated when the form is first displayed, so it will contain the actual URL of the page where the form is embedded.
