Support » Plugin: Admin Columns » WP Debug Notice

  • Resolved Robert Reiser


    Hello AdminColumns team,

    This is purely FYI, nothing is broken at this point:

    On my development site I have WP_DEBUG enabled, and I can see the following notice on the top of my admin screens:

    Notice: AC_ListScreen_Media is a is a deprecated class since version 4.3! Use AC\ListScreen\Media instead. in /var/www/html/*****/wp-content/plugins/codepress-admin-columns/classes/Autoloader/Underscore.php on line 132

    Just bringing this to your awareness.

    Kind regards,

    Hi Robert,

    Thanks for your feedback. This is a notice that points developers that use our plugin have to change their code.

    As the notice says we changed all our internal classes to namespace classes. This is change in all our code, but there might be other plugins or maybe some custom code in your theme that is using our old classes.

    Do you maybe use the plugin ‘Media Library Assistant’? Because I know this plugin use this specific class. Otherwise, could you have a look in your own code for AC_ListScreen_Media and change it to AC\ListScreen\Media?


    Hello Stefan,

    thanks for getting back to me – indeed I am using the MLA plugin, and I will make them aware of this as well.

    Thanks for the response,
