 * Hey guys,
 * looks like that the plugin is not compatible with PHP8. When I try to visit the
   plugin-settings, I get
 * `Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback)
   must be a valid callback, non-static method sg_subscribe_settings::options_page()
   cannot be called statically in /wp-includes/class-wp-hook.php:307 Stack trace:#
   0 /wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters('', Array) #1 /
   wp-includes/plugin.php(476): WP_Hook->do_action(Array) #2 /wp-admin/admin.php(
   259): do_action('settings_page_s...') #3 /wp-admin/options-general.php(10): require_once('/
   p...') #4 {main} thrown in /wp-includes/class-wp-hook.php on line 307`
 * Tried to look into the code, but was not able to find a fix (I’m not a developer
   nor do I have any experience in PHP-development)
 * Final result at least for me:
 * – you can not configure the settings for the plugin
    – (and with that) also not
   make it work for the frontend
