 * Today I visited My Website that I created and i’m using Multiple Theme plugin
   in it but i found the website isn’t working and i found this message in the settings
   of the plugin 
   Deprecated: Function unregister_setting was called with an argument
   that is deprecated since version 4.7.0! $sanitize_callback is deprecated. The
   callback from register_setting() is used instead. in /home/rasans/public_html/
   wp-includes/functions.php on line 6031
