Call to undefined method vB_HumanVerify_Abstract

[NSanityHD]

After installing some modifications and upgrading to vBulletin 3.8.11 (I don't really like vB4+) and installing some SEO module, spam prevention and Google/Facebook login products, when someone goes to register they get a fatal error. :/ I've included screenshots of the error and the list of products installed.

I thank anyone who can help!


EDIT: I should note that I followed the documentation on Google to the letter and yet I'm getting this issue. This is what is on line 8 - 14:

class vB_HumanVerify_New_Recaptcha extends vB_HumanVerify_Abstract
{
    public static $verify_url = 'https://www.google.com/recaptcha/api/siteverify';

    function vB_HumanVerify_New_Recaptcha(&$registry)
    {
        parent::vB_HumanVerify_Abstract($registry);
    } 

        parent::vB_HumanVerify_Abstract($registry); 

^ being line 14.

That isn't vBulletin 3.8.11 code. Newer versions of PHP do not allow constructors to have the same name as the class they are constructing. The new code should look like this:

class vB_HumanVerify_Recaptcha extends vB_HumanVerify_Abstract
{
    /**
    * Constructor
    *
    * [USER="147035"]return[/USER]   void
    */
    function __construct(&$registry)
    {
        parent::__construct($registry);
    }

{
parent::__construct($registry);
}

What would I do to resolve this then? I've had to disable the reCaptcha and use questions instead for now. :/

Replace your files with the default vBulletin files in the 3.8.11 package. If it is from an addon, you'll need to update it to current coding standards.
