Recaptcha error with WPforms plugin

Hi,

I’m using Blocksy with the WPforms plugin for contact forms. I’m experiencing the following error: “Google reCAPTCHA verification failed, please try again later.”

I’ve deactivated all plugins apart from WPforms, and I still get the error. I’ve purged caching plugins and browser cache, and I’ve swapped to other themes. The only thing that works is using another theme (the contact form submits), so I assume it’s a conflict with Blocksy.

Any suggestions?
