 * Good day Mr. Raschendorfer,
 * during our debug control routine we get the following warning:
 * Warning: Undefined array key “SERVER_ADDR” in /some/path/wp-content/plugins/smart-
   user-slug-hider/inc/class-smart-user-slug-hider.php on line 53
 * We prefer to have this fixed at the code level before reaching out to our server
   colleagues.
 * Please give us some feedback.
   Thank you very much!

   let me know if it works for you.
