Changed site name and now can't preview site

Hello, I recently changed the site name so it would stop showing up in search results. I knew it would pull some threads on the back end but am way out of my pay grade to figure out which threads are affected. Should I delete all the custom code or is there a simple fix? I'm able to see the site through safe mode and it's still online. Thank you in advance.

Can you share your website URL?

What did you change, just the site title in the header settings?

Hi Ziggy and thank you for responding. I changed it in the domains & email section.

It looks like an error with your plugin from SF Digital @paul2009 you'll need to update your changed built in domain with that plugin.

If you type your website URL in you will see the error message:

https://aharamushrooms.squarespace.com

Thank you Ziggy, I had totally forgotten about that Shopify buy button code.
