Not working with valid configuration

Hi,

Thank you for contacting us!

Please make sure that “Site key” and “Secret key” are specified correctly on the plugin settings page.
You can take them here – https://www.google.com/recaptcha/admin#list. If keys are correct, but the problem still remains, please try to generate new keys and enter them on the plugin settings page.
Also, check the reCAPTCHA version you generated the keys for. The Version should be the same on the plugin settings page and here – https://www.google.com/recaptcha/admin#list.

Please note that the compatibility with WooCommerce is not available in Free plugin version: https://bestwebsoft.com/products/wordpress/plugins/google-captcha/.

Let us know about the results.
