    I think your plugin is great and uncomplicated because I can use an existing page as a coming soon page. Could I ask you to eliminate this error?

    Warning: Undefined array key 0 in /home/httpd/vhosts/badundraum.ch/boffi-sg.ch/wp-content/plugins/bw-coming-soon-page/includes/plugin-settings.php on line 11

    Please update your Plugin “Coming soon Page”. ??

    To fix this bug, you should make sure that the array is not empty before accessing its elements. You can do this as follows:

    $current_user = wp_get_current_user();
    $current_user_role = isset($current_user->roles[0]) ? $current_user->roles[0] : '';

    This change first checks whether the array roles even has an element at position 0 before it is accessed. If the array is empty, an empty character string (”) is assigned.
