Warning: call_user_func_array() expects parameter 1 to be a valid callback

  • I’m getting an error message on my wordpress dashboard page:

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘mythemes_gallery’ not found in /srv/disk5/2743089/www/ferndaletabletennis.sportsontheweb.net/wp-includes/class-wp-hook.php on line 286

    It doesn’t seem to be causing any problems on my actual website but it’s still making me nervous. I’d rather not dig in to code. Any ideas?

    Treeson is Version: 0.1.16
    Wordpress is version 4.9.6
    All other plugins are also up to date.

    The page I need help with: [log in to see the link]
