reCAPTCHA issue

[TinFoilLord]

reCAPTCHA keeps saying the captcha has been inputted incorrectly, however that is not the case.

 

I don't see what's wrong with it, I've been trying for hours, looked all over and not found a solution to my problem, so I decided I'd ask here, after hours of no luck on IRC.

 

 

 

Verify.php code:

 <?php
 require_once('recaptchalib.php');
 $privatekey = "snip";
 $resp = recaptcha_check_answer ($privatekey,
                                 $_SERVER["REMOTE_ADDR"],
                                 $_POST["recaptcha_challenge_field"],
                                 $_POST["recaptcha_response_field"]);
 if (!$resp->is_valid) {
   // What happens when the CAPTCHA was entered incorrectly
   die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
        "(reCAPTCHA said: " . $resp->error . ")");
 } else {
   //snip

 }
 ?>

Form code:

	<form class="email" action="verify.php">
		<input type="text" name="email" class="field" onfocus="if(this.value=='Get Notified (Email Address)') this.value='';" onblur="if(this.value=='' || this.value==' ') this.value='Get Notified (Email Address)';" value="Get Notified (Email Address)" />
		<input type="submit" class="submit2"  /><br />
