Hi rubercyb2
You may look at this file: /administrator/components/com_t4pagebuilder/libs/Editor/Action/Contact.php
//Collecting the status
switch ($httpCode) {
case 200:
$msg = ['message'=>'Success, newsletter subcribed using mailchimp API'];
break;
case 214:
$msg = ['message'=>'Already Subscribed'];
break;
default:
$msg = ['error' => 'Oop, Email can not subscribe. Please contact the admin'];
break;
}
}else{
$msg = ['error'=> 'Oops, please try again. Please add email'];
}
and translate there.
