PHP Notice: Undefined index: SERVER_ADDR

  • Hi,

    we are using this plugin on an up to date WordPress page, with PHP 7.4 and nginx.
    Our debug.log is filled with notices from this plugin:

    PHP Notice: Undefined index: SERVER_ADDR
    Path: smart-user-slug-hider/inc/class-smart-user-slug-hider.php

    The $_SERVER['SERVER_ADDR']; variable can be used without any problems by PHP files.

    It would be great to have this fixed and also have this plugin tested with the most current WordPress version.

    Thanks!
