Hi,
Let's check on this post:
https://stackoverflow.com/questions/30735694/recaptcha-error-invalid-domain-for-site-key
It seems that's an issue with your reCAPTCHA from google recaptcha, have you use google recaptcha on your site?
Because your site has this issue when load on Tor browsers - check this image
And it's not related with the theme itself.
Best Regards,
