I mean it might be a search setting related to that, but I'm not sure.
Can you please try the following:
– disable the W3TC plugin temporary, and check if the search works then?
There are no error messages in the console, it is just not returning any results. If you want, you can provide temporary admin and FTP access and I will debug through the search code to see if there is anything wrong. You can edit your first post in this thread or upload a .txt file with the details – both methods are safe and only visible to me and you.Best,
