 * May be the folder structure of the plugin is incorrect.
 * Review the [Plugin Handbook](https://developer.wordpress.org/plugins/) and see
   if missing anything.
 * Also, review [https://developer.wordpress.org/plugins/wordpress-org/plugin-developer-faq/](https://developer.wordpress.org/plugins/wordpress-org/plugin-developer-faq/)
