Can’t anymore login

I had the same error and I simply disabled the plugin by change it name to something else. May be plugins js is cached somewhere. its better to purge all cache and test it. it should work.

I can confirm plugin works fine after I followed these steps.
1) Disable the plugin from the plugins folder by renaming it.
2) Login to wordpress admin and clear all cache w3total cache or WPRocket etc
3) Rename the plugin name back to “google-captcha”
4) Activate the plugin.
5) Click save settings without modify anything.
6) Logout and login back to test it

cheers

In order to access your dashboard, it is necessary to deactivate plugin manually. Please complete the following steps:
1) Go to the your_wp_root/wp-content/plugins folder via FTP (https://codex.www.ads-software.com/FTP_Clients);
2) Find and rename “google-captcha” folder into “google-captcha1”;
3) After you log into your dashboard, you can rename the folder back.

Please make sure you have correct “Site key” and “Secret key” entered on the plugin settings page. Get correct keys you can here – https://www.google.com/recaptcha/admin#list. If you sure the keys are correct, provide a link to the login page (the plugin should be activated), and we’ll try to detect the problem.
