Problem solved
Thanks to @TomJNowell
Solution:

  1. make a directory under the wp-content directory and name it mu-plugins
  2. then move your plugin directory (for example woocommerce) in wp-content/mu-plugins
  3. after that you have to call it for your WordPress by crating a file and name it load.php
  4. introduce the plugin bin load.php for example:

<?php require WPMU_PLUGIN_DIR.'/woocommerce/woocommerce.php';

Done 🙂
