Can you give us the debugging output for the request?

Sorry but it doesn't generate logs. But i have narrowed down the problem to the
$answers response from the server. It appears that the array values for 
$answers[0]
and $answers[1] are both null which triggers the $recaptcha_response->is_valid =
false; else statement on line 188 of recaptchalib.php.

Hi,

Are you sending a Host header? It would really help us if we could see the full 
HTTP
request that you are making.

Here is the request that I'm making. This is generated using my debugging 
software
hence the localhost IP address but i am experiencing this problem on my live 
server
too.

Thanks. The issue is that you aren't sending a Host header of 
api-verify.recaptcha.net. 
The latest version of the PHP plugin shouldn't be doing this, did you make 
custom 
modifications?

I must have been without realizing it. I have just replaced my recaptchalib.php 
with
a new copy and everything seems to be working again. Thank you for your help and
patience.
