JS Events stopped working

Hi. I have split your reply from that thread so that we can address your issue directly. Could you further describe what you had working, and what has gone wrong?

Are you able to send me a live link/URL to your search page so I can take a look?

Can you upgrade the plugin to v2.5.2 and also try adding this plugin:

https://wordpress.org/plugins/enable-jquery-migrate-helper/

See if that helps?

Can you try deactivating as many plugins as possible and testing?

Can you change the code to only this and test:

(function ( $ ) {
  "use strict";
  console.log("ajax complete");
  $(document).on("sf:ajaxfinish", ".searchandfilter", function(){
    // nothing here
  });
}(jQuery));
