sitekey for this hCaptcha is incorrect

Hello,

I get a message:

The sitekey for this hCaptcha is incorrect. Please contact the site admin if you see this.

I’ve entered the correct sitekey and secret key and added the site to the domains in hCaptcha but it still doesn’t work.

I’ve also tried archiving the default sitekey and adding a new site and making sure the right domain is in the list of hostnames but it still says the same thing.

I’ve cleared all caches, cookies and tried different browsers.
