Undefined index

Version 3.7.4 should fix it.

Getting all sorts of these errors:

Notice: Undefined index: profile_error in /var/www/html/wp-content/plugins/newsletter/subscription/subscription.php on line 652

Notice: Undefined index: profile_error in /var/www/html/wp-content/plugins/newsletter/subscription/subscription.php on line 652

Notice: Undefined index: sender_email in /var/www/html/wp-content/plugins/newsletter/main/diagnostic.php on line 93

Notice: Undefined property: NewsletterControls::$errors in /var/www/html/wp-content/plugins/newsletter/main/diagnostic.php on line 105

Upon reinstalling the plugin and trying to save the return email, this is what I get after saving:

Notice: Undefined property: NewsletterControls::$messages in /var/www/html/wp-content/plugins/newsletter/main/main.php on line 51
