Error after updating to PHP8

  • After attempting to update a site to PHP 8.2 from 7.4 I’m getting the following error message related to the plugin: Warning: Undefined array key “visitor” in /…/wp-content/plugins/holler-box/includes/class-holler-popup.php on line 571.

    If I deactivate the plugin I am able to update without issue. Is there an update in the works to fix this?
