Undefined array key “HTTP_REFERER” or “HTTP_ORIGIN” with PHP >= 8.0

  • Hello,
    From PHP version 8.0 and upper, I receive warnings displays in spite of having setting WP_DEBUG and WP_DEBUG_DISPLAY to false, it’s annoying.

    Undefined array key “HTTP_REFERER” in?/wp-content/plugins/wp-cors/wp-cors.php?on line?28
    Undefined array key “HTTP_ORIGIN” in?/wp-content/wp-cors/wp-cors.php?on line?29

    How can I solve this problem?
    Thank’s.
