[Solved] reCaptcha validation fails. Error code: invalid-json
I get this error when I try to submit a comment as guest.
I double checked and my reCAPTCHA V2 API keys are correct.
The domain is correctly associated with reCAPTCHA, infact I am using reCAPTCHA also with WPForo and other plugins with no issues.
Anything specific I should check?

What version you use? Have you updated to the 7.0.1 version.
Please navigate to Dashboard > wpDiscuz > Settings > Google reCAPTCHA admin page, find the "Request method" option and change the value of the option to "CurlPost", delete all caches and check again.
If it doesn't help select the values one by one to find the request method that will work fine in your case.
Press CTRL+F5 (twice) on the frontend each time before checking.
