I’m consistently having issues with my forms appearing on my Wordpress site. I’m using the GroupDocs plugin, and without warning, a form will throw an error “This form does not exist,” or an unknown error and the form doesn’t load. And none of the links to “get in touch” work when this happens. However, if I repaste the form ID number (the exact one that’s already listed in the shortcode on teh page), the form loads.
