Hi Judy,
Checking your site, I can see that the code in your functions.php are currently not commented out.
Also there’s errors leading to your custom code as well: https://share.getcloudapp.com/nOuXm6NG
Can you try commenting out your custom code once more, and then, clear your CDN cache and server side(hosting provider) cache if any.
View this to see your site is displaying a cached version: https://share.getcloudapp.com/yAu1LGlk
You can also try clearing these caches out first before commenting the code out. Then redo it after commenting the code out.
Kindly let us know how it goes.
