Reply To: Changing scripts

Hello,

You need to add the custom PHP code to the functions.php of the child theme in Appearance > Edit theme.

You can find more details here: https://developer.wordpress.org/themes/advanced-topics/child-themes/

If you need to add JS code, you need to add it to the Theme Settings > Custom JS.

If you have any questions please feel free to contact us.

Best Regards
