Replace:

PHP Code:

eval('$form[\'hiddenfields\'] .= "' . fetch_template('subscription_payment_rbspoint') . '";'); 


with:

PHP Code:

$templater = vB_Template::create('subscription_payment_rbspoint');
form['hiddenfields'] .= $templater->render(); 


You may need to register some variables for the template to make use of them, the parameters would be the ones to look at. That message is a warning and not an error, so you could leave it as is.
