When users submit the forms, I have a success message appear which I entered in POST SETTINGS–>Redirect to same page–> message to show.
The issue is when form is submitted and the success message is shown — apparently there's a character limit on the message or the box revealing the message isn't large enough. How do I fix that to show the entire success message?
Actually there isn't any character limit there. As we are saving the form settings in custom field, your message might be long enough to break the limit of custom field. So it might be cutting off large messages automatically.
