  • v4.2.5 not working with Recaptcha v2 - 404 error

    Hi,

    My forum is becoming overrun with bot signups - 1200 in a day! I was using the older image verification which clearly doesn't work very well.

    I am trying to switch to Recaptcha v2 (as I believe v3 is not supported by my vBulletin v4 software) and have setup the keys in the human verification manager screen. But when you try to sign up, there is nothing shown in the UI and the console shows a 404 error hitting GET https://www.google.com/recaptcha/api/challenge?k=<my key>

    The line throwing the error is in the register.php file: <script type="text/javascript" src="https://www.google.com/recaptcha/api/challenge?k=<my key>>

    I've had to disable new signups because of the spam, so any advice on how to get Recaptcha working or how otherwise to prevent bot signups is much appreciated.

    Thanks!

    Those URLs are for ReCaptchav1. Google has taken them offline. I am pretty sure that vBulletin 4 does not support ReCaptchav2 out of the box. There hasn't been major development on vBulletin 4 since 2012. I cannot see any reference to it in the AdminCP code for verify.php.

    Here is an addon that adds this functionality - https://www.vbulletin.org/forum/showthread.php?t=315960

    I don't know if it works on newer versions of PHP though.

    Another addon that may be helpful is this one: https://www.vbulletin.org/forum/showthread.php?t=248042

    Functionality similar to both of these addons are native in vBulletin 5 and guaranteed to work with the latest versions of PHP.

      I use KeyCaptcha as have vBSecurity from DBTech, and Spam-O-Matic. It appears Google is neglecting and not updating reCAPTCHA v2 as a lot of spambots can easily bypass that filter.

        vBulletin 4 doesn't support ReCaptcha2 as far as I am aware. The original Recaptcha servers were shut down.

        I can't provide support for KeyCaptcha or the addons you have installed. This functionality is built into vBulletin 5.
