>> Integration ? Pro Answer ? Thank you

Fantastic plugin , I got a popup login form

1. I add the php script to display the recaptcha : OK
<?php
$attr = array(
‘data-theme’ => ‘white’,
);
do_action( ‘recaptcha_print’ , $attr );
?>
2. it ask to select 3 images as usual : OK
3. I press validate and it say in red : ” Error: the Captcha didn’t verify.”

How can I do to make it work ?

Thank you
