Error, Plugin Not Working

  • Hi, so I’ve installed it, and next to the setting “Estimated Delivery Time in Days”, it says the following:

    Warning: call_user_func() expects parameter 1 to be a valid callback, class ‘WeDevs_Settings_API’ does not have a method ‘callback_number’ in /home/xxx/public_html/mywebsite/wp-admin/includes/template.php on line 1388

    Any idea how to get this working?
