 * I noticed my debug.log was almost 4GB (!!!) and it’s full of this php warning:
   undefined array key.
 * PHP Warning: Undefined array key “title”
    PHP Warning: Undefined array key “topicid”
   PHP Warning: Undefined array key “url”
 * They all point to plugins/wpforo/wpf-includes/functions-template.php file.
 * Any ideas how troubleshoot this warning? What might be causing it?
