Where To Put The Code Snippet?

This code snippet should go in your active theme’s functions.php file.

Add it to the bottom of the file, before any closing ?> characters.

It’s always a good idea to take a backup of your functions.php file in case anything goes wrong – you can just copy the old code back in again.
