Getting Invalid Captcha code every time

Please navigate in Dashboard to Comments > Settings > Hide/Show Tab and change CAPTCHA generation type to “use wordpress session” then ave it, delete all caches and do Ctrl+F5 on post front-end.

I had it set to “use wordpress session” so I set it to the other option – use file system. That seemed to fix the problem but not before my homepage got deleted for some reason. Not sure if it is related but as soon as I made the change then purged cache it went missing. I’m 100% positive I did not make any other changes. I went to will2walk.org and my homepage was missing. Have you heard of this happening before?

Please change it back to session and test again or you can deactivate it. wpDiscuz doesn’t have any chance to affect your home page.

changed it back to “session” and still getting invalid captcha every time. please advise.

I just asked to change it back to see if the home still affected or not. Please use the file mode. The session doesn’t work for you.

Hi,
I have installed the plugin and I had selected ‘use wordpress session’ to generate captcha image.
N.B: My thing has been hosted at Pantheon, so you can understand I can’t change any file/folder permission at test and live instances.
Though, I had chosen ‘use wordpress session’ to get the usual result properly at dev.
But, every time I try to validate the captcha, it says Invalid Captcha error!
I have been digging the code and found the session variable $_SESSION[‘wpdiscuzc’][$key] doesn’t get evaluated at utils/captcha/captcha.php.
$sCaptcha = isset($_SESSION[‘wpdiscuzc’][$cnonce]) ? $_SESSION[‘wpdiscuzc’][$cnonce] : false; at forms/wpdFormAttr/Field/DefaultField/Captcha.php should carry the value of $_SESSION[‘wpdiscuzc’][$key].
So while validating manual entry (i.e the captcha string we put at the comment form) with the session value, it return false i.e satisfying
if (!$sCaptcha || md5(strtolower($captcha)) !== $sCaptcha) {
$messageArray[‘code’] = ‘wc_invalid_captcha’;
wp_die(json_encode($messageArray));
}
end error appears.
So, is there any solution at your end?
N.B: I can debug print_r($_SESSION); at forms/wpdFormAttr/Field/DefaultField/Captcha.php but do receive nothing at utils/captcha/captcha.php!
