Wops! Yes, that’s what it was. I was following the official documentation (https://documentation.ajaxsearchpro.com/layout-settings/auto-populate-automatic-search-results-on-initial-page-load) and it says ‘leave this empty’ (on the screenshot) so that’s what I did. I’m glad it’s a simple thing to do. However, I would recommend that you specify on that page that by empty you mean a space so it would be a bit easier to understand.
Anyway, thanks for the help!
