Sorry about that. Done. Did you want to post an article as well?

Also I was testing it on my development server so I could update Geeklog.net and I noticed that I keep getting an error message of the captcha being expired when I enter a captcha for a comment or a new user (that is all I tested the captcha on).

With logging enabled I also get the message in the captcha log file:

CAPTCHA: Detected an attempt to use an expired CAPTCHA in comment - IP Address:

This was an upgrade from 3.4.0 I believe and the previous version was working.

I also checked the captcha table and their is a record with the correct captcha code and I assume the correct session id.

Angry I sent you a new archive. A $_CP_CONF['expire'] was missing. Everything seems to work now on my testing platform.

Yup it works. I updated the download on Geeklog.net with the new version (3.4.1).

Feature request:

For some reason Google has stated crawling my installed captcha plugin:

/captcha/captcha.php
/captcha/captcha.php?c

When accessed directly if produces the error (which Google complains about in Webmaster Tools):

Invalid session id

Can we return a 404 error if it is accessed directly? Geeklog 2.0 has the new function COM_handle404 which is used by all of the core plugins.

As COM_handle404 function seems to be only available for Geeklog 2.1 I will add this feature in the next release.

In captcha.php file start by:

Text Formatted Code

if (strpos(strtolower($_SERVER['PHP_SELF']), 'captcha.php') !== false) {
    COM_handle404();
}


meanwhile we can add in the curent release

Text Formatted Code

if (strpos(strtolower($_SERVER['PHP_SELF']), 'captcha.php') !== false) {
   die('This file can not be used on its own!');
}

Actually that doesn't work since that file gets called by the script through html

For now I have just replaced

die("Invalid session id"Wink;

with

COM_handle404();

+1 Smile

Text Formatted Code
// see if an existing session_id is passed
if (isset($_GET['csid']) ) {
    $csid = COM_applyFilter($_GET['csid']);
} else {
    COM_handle404();
}
