What should I do if I use SiteOrigin Page Builder and added form shortcode do not work properly?
For some purposes SiteOrigin Page Builder add
<br /> html-tags inside our form if you use it as shordcode. In can be cause of multiple issues, so prefered to use our form as widget rather than shortcode in case if you use this plugin.
If you have issues with blank simple CAPTCHA (symbols or numeric), try to use reCAPTCHA.
