Hi, when i click on “Customizer” (and some other), this PHP-Error occurs:

Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($function) must be a valid callback, function “vw_kids_customize_controls_register_scripts” not found or invalid function name in /home/.sites/757/site7634390/web/wp-includes/class-wp-hook.php:303 Stack trace: #0 /home/.sites/757/site7634390/web/wp-includes/class-wp-hook.php(327): WP_Hook->apply_filters(NULL, Array) #1 /home/.sites/757/site7634390/web/wp-includes/plugin.php(470): WP_Hook->do_action(Array) #2 /home/.sites/757/site7634390/web/wp-admin/customize.php(123): do_action(‘customize_contr…’) #3 {main} thrown in /home/.sites/757/site7634390/web/wp-includes/class-wp-hook.php on line 303
