Registration reCAPTCHA is always wrong

Hi everybody,

I recently install an Openfire 3.8.2 with Registration 1.5.0 plugin, everything works perfect except that reCAPTCHA is always wrong, I have create and re create the reCAPTCHA account and get the public and private keys, but no matter how many times you try is always wrong, if I deactivate reCAPTCHA registration works.

No messages in any Openfire log when this error occurs.

Have anybody has this same situation? Or know for any solution?

Thanks in advance for your help.

David
