  I’m seeing repeated warnings on my site related to the Wishlist plugin. They mention something about an “undefined array key ‘id’.” This happens when someone tries to add or remove items from the wishlist.

  I’m running PHP 8.3, and it seems the plugin is trying to use something that doesn’t exist yet, which causes the warnings. The site still works, but the logs are full of these messages, and I’m concerned it could cause problems later.

  Could you provide a fix or update so the plugin works cleanly with PHP 8.3 as all my sites use PHP8xx as default and we really don’t want to be editing core files.

  Thanks!
