According to Google, reCAPTCHA v1 support will no longer be available after March 31, 2018. And we have just updated our plugin for WebMail Pro and Aurora, it now supports version 2 of Google reCAPTCHA.
You can find the plugin and its documentation at:
https://afterlogic.com/docs/plugins-repository/displaying-captcha-on-login-screen
If you have previously used plugin that works with reCAPTCHA v1, be sure to update the plugin and get v2 keys from Google reCAPTCHA website.
