I get this error:
Theme cannot be previewed because it's missing one of these required files: layout/theme.liquid, config/settings_schema.json
Not sure how to fix this. I viewed the code and didn't see any errors.
If it's a preview others wont be able to investigate the problem even with the website url.
You need to rollback your theme if you cannot figure out the error or provide better detail as to what you have done.
