API key problems

[asdffdsa]

Hi, I just signed up for reCaptcha today and implemented it into my
website. Everytime I tdo the captcha, I get this error: “To use
reCAPTCHA you must get an API key from https://www.google.com/recaptcha/admin/create”/



I triple checked all the code, all my keys were put in correctly.



Thanks

First, is the API key matched to your domain name correctly?

Second, you may want to post some code and let someone look at it with
"fresh eyes".

Yup, the domain name is correct

First, is the API key matched to your domain name correctly?

Yes, I'm certain they're matched correctly, I checked dozens of times.
