KeyCAPTCHA is preventing access to the site.

Hello, Ivan! There is a problem with the captcha. I set up a key captcha (the images are not visible for some reason, and the site for that captcha also doesn't work when trying to log in) and now I can't access my site... what a mess... in hindsight, I'm thinking that I should have used a regular captcha for logging in. Is there any way to disable this type of captcha?
