Error message in modules.php

Hello!

There is an error that occurs when a non-newsletter user tries to access the newsletter profile page.

Notice: Trying to get property 'token' of non-object in /customers/e/0/e/[redacted]/httpd.www/wp-content/plugins/newsletter/includes/module.php on line 952

The line 952 has the check: if($token != $user->token) which throws as error since $user isn’t set when there’s no newsletter user.

Until it’s fixed, I added and extra if statement to check if $user is set to prevent the error message being shown.

if(isset($user)){
  if ($token != $user->token) {
     $user = null;
  }
}
else{
  $user = null;
}
