Everton,<br>
<br>
I've just had a dig through my mail archives.<br>
<br>
Some folks at Brunel University in the UK had the same problem. Here
is their comment on the problem and how they fixed it:<br>
<br>
<font color="red">Reason for reCAPTCHA problem we understood relates
to the firewall and IPV6 settings.<br>
Recently we had firewall and network changes implemented to our
data centre which had impact on IPV6 related connectivity in Linux
environment.<br>
We have disabled IPV6 on dropoff server and it worked fine without
any issues. <br>
</font><br>
Hope that helps,<br>
Jules.<br>

<div> Hi Everton,<br>
<br>
I've just compared the code from 5.03 to the latest, for
this specific problem.<br>
<br>
Try applying this patch (manually with a text editor is just
fine!) to /opt/zendto/www/verify.php:<br>
<br>
<tt>97,101c110,111</tt><tt><br>
</tt><tt>< // Old version 1 code.</tt><tt><br>
</tt><tt>< // $resp =
recaptcha_check_answer($reCaptchaPrivateKey,</tt><tt><br>
</tt><tt>< //
getClientIP(),</tt><tt><br>
</tt><tt>< //
$_POST["g-recaptcha-response"]);</tt><tt><br>
</tt><tt>< $recaptcha = new
\ReCaptcha\ReCaptcha($reCaptchaPrivateKey);</tt><tt><br>
</tt><tt>---</tt><tt><br>
</tt><tt>> $recaptcha = new
\ReCaptcha\ReCaptcha($reCaptchaPrivateKey,</tt><tt><br>
</tt><tt>> new
\ReCaptcha\RequestMethod\CurlPost());</tt><br>
<br>
If that helps, apply this (very similar) patch to
/opt/zendto/www/pickup.php as that's the other place this
call appears:<br>
<br>
<tt>130c143,144</tt><tt><br>
</tt><tt>< $recaptcha = new
\ReCaptcha\ReCaptcha($reCaptchaPrivateKey);</tt><tt><br>
</tt><tt>---</tt><tt><br>
</tt><tt>> $recaptcha = new
\ReCaptcha\ReCaptcha($reCaptchaPrivateKey,</tt><tt><br>
</tt><tt>> new
\ReCaptcha\RequestMethod\CurlPost());</tt><br>
<br>
I've never managed to figure out why sites which have been
working perfectly well on the default suddenly stop doing
so, with apparently no changes anywhere (except at Google?).
But using the CurlPost() technique seems to work well for
everyone.<br>
<br>
Let me know how you get on.<br>
<br>
Cheers,<br>
Jules.<br>

Please can you try a couple of things:<br>
1. Close all your browser tabs except 1 showing
something like Google's home page. Clear your
browser cache completely, then quit and restart your
browser. Does the problem still occur?<br>
2. Try from an incognito/private browser window.
Does that make it behave?<br>
<br>
If number 2 makes it behave, then the browser cache
isn't being fully cleared, as that's the only
important difference as far as a new tab is
concerned.<br>
<br>
Anyone else seeing this problem?<br>
<br>
Cheers,<br>
Jules.<br>
