 * Hi, can anyone give me some information?
 * So I have 2 domains, domain 1 in the plug-in menu does not show a drop-in while
   domain 1 again in the plugin menu appears a drop-in with 1 item, namely advanced-
   cache.php, more clearly can see the picture from this link:
 * [https://kevdees.com/what-are-wordpress-drop-in-plugins/#:~:text=WordPress%20drop%2Din%20plugins%20are,developers%20or%20other%20regular%20plugins.&text=For%20example%2C%20you%20can%20use,file%20and%20it’s%20wpdb%20class](https://kevdees.com/what-are-wordpress-drop-in-plugins/#:~:text=WordPress%20drop%2Din%20plugins%20are,developers%20or%20other%20regular%20plugins.&text=For%20example%2C%20you%20can%20use,file%20and%20it’s%20wpdb%20class).
 * I’ve read the article on the link but don’t understand the function of the wordpress
   drop-in plugin feature for what and why it can appear while the domain 1 again
   doesn’t appear.
 * Next, how to bring up and remove these features?
 * thanks!

 * [@guhz](https://wordpress.org/support/users/guhz/) Drop-in plugins are PHP files
   to enhance WordPress functionality. You cannot really update or delete them via
   UI. You will need to move them via FTP. You can further read about it here: [https://kraft.blog/2018/05/wordpress-drop-in-plugins/](https://kraft.blog/2018/05/wordpress-drop-in-plugins/)
 * Let me know if it helps.
