I’ve found a previous post where the same issue occurred. My server has been investigated and it’s not causing any issues. Can you please confirm if this is an issue with the form itself on your side?
This is not the case. The form works, I have tested it many times. Messages come through in my email inbox so it is not a hosting problem. The issue is simply the button showing the error symbol. I have spoken with the hosting provider, it is not a problem on their side.
Issue still exists. I re-added the original shortcode and when I press submit, an error icon shows on the button. Also how can the submit button be moved to the center?
