reCAPTCHA couldn’t find user-provided function: onloadCallback

The default login form does not respect the recaptcha extension. I can log in without the security and after logging in the console only the message “reCAPTCHA could not find user-provided function: onloadCallback” is visible.
I’ve tried to reinstall the plugin and extension, disable other plugins to check collisions, but nothing helps.
Can you help? What data do you need?
