PHP Warning: Undefined array key “HTTP_HOST”

  • Hello,
    We are getting this in the log again and again:

    [21-Sep-2023 10:14:25 UTC] PHP Warning:  Undefined array key "HTTP_HOST" in /home/japaneseknives/public_html/wp-content/plugins/wp-cerber/cerber-load.php on line 7699

    We are using version 9.5.7.

    How can this be resolved?

    Thank you
