i am tried "product-kh99_new_recaptcha_v1_0.xml" worked admincp. Please , "class_humanverify_new_recaptcha.php" edit the file for Vb Version 3.7x?
(turkce bilen arkadaslara da sorayim. Bu dosya 3.7.4 un admincp modulunde calisti. Ancak includes'e atilan php dosyasi 3.7 ye gore olmadigindan satirlara hata veriyor. Bunu duzenleyebilecek, yada yardim edebilecek biri var mi? Tesekkurler )

I tried Test Configuration and got this error:
Does anyone know how to fix this?

Contact your host. Curl is a PHP option. They need to add it to your server.

I'm running a VPS, is there an easy way I can do this myself?

You'll need root server access. You can research how to install a LAMP stack on Google. You'll only need to know the P portion of the LAMP stack installation instructions. You can find detailed information at php.net

You may be able to do it through WHM if you have access to that. What you'll need to do is recompile Apache / PHP... if you have WHM and Easy Apache, that may allow you to do it.

But I suspect your host would prefer you let their tech support people do it.

It works, but sets the usergroup to Banned even after the user clicks the activation link in the registration email. When the user goes to the forum, he/she is told they are banned. What have I done wrong??
