{
    //unset($list[0]);
    $list[] = 'register_form';

    return $list;
}

add_action('sgr_render_list', 'customSgrRenderList');

function customSgrVerifyList(array $list): array //Where reCAPTCHA is verified
{
    //unset($list[0]);
    $list[] = 'lostpassword_post';

    return $list;
}

add_action('sgr_verify_list', 'customSgrVerifyList');

Variable $list is array of default hooks, indexed by numbers.

Prevents from posting comments

When I try to post a comment, I got this error : Google reCAPTCHA vérification échouée. Le paramètre de réponse est non valide ou malformé. (I use recaptchaV3)

Hm, something fishy, but ok

After installing this plugin, the limit logins spikes up. I'm not 100% sure of this, but I've noticed it on several webistes I edit. Maybe something to look into. As plugin itself, it is ok, but something not right realted to spikes in fake logins.

Best reCAPTCHA Plugin Period

10 novembra, 2022 1 reply
I need to donate a few dollars to this guy. I don't normally comment on plugins unless they just stand out. reCAPTCHA plugins should be simple and this one is. It's rare to see plugins that just do what they are supposed to without adding all this extra crap to them so they can vomit wordpress notifications at you to buy something with pro to the end of the name. To be honest, do I really need a plugin to add reCAPTCHA to my site? NO, but clients appreciate it. The less code or scripts I have to explain the better. This is one of my favorite apps. If I ever get more spare time I'd love to help this developer continue this project into the future. Thank you Michal Novák maintaining this plugin.

The most easier recaptcha plugin

28 septembra, 2022 1 reply
This ReCaptcha is the most straightforward I have ever seen. It would be great if I could set the link in the note open in a new tab. I mean this --> This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply. Currently it is open in the same tab which I don't wish to.

Easy to use
