Instant search bar not showing on 1 of the sites

I have an issue with the Instant Search plugin not showing on the website front page.
Using Instant Search through the Emporium Theme on NopCommerce 4.30. There is not a single error to be found in  any log (not NOP logs, not system logs, not IIS logs) and the search bar works fine on other sites with the same configuration. How do I figure out what goes wrong here...

Greetings,

Thanks for the reply.
For others having this issue,

we figured it out, it was a conflicting search setting in NOP somewhere else.
