Hi! I installed this plugin in the widget area and when clicked in the submit button gives errors:
Notice: Undefined variable: prefix in /home/aureacen/public_html/lab/wp/wp-content/plugins/newsletter/subscription/subscription.php on line 453
Notice: Undefined variable: prefix in /home/aureacen/public_html/lab/wp/wp-content/plugins/newsletter/subscription/subscription.php on line 455

I don´t know if I configured something wrong or what’s the problem. Can somebody help me?
Thanks!
