Hi,
In order to get result sort by Most recent First, go to backend >> Components >> JA K2 Filter >> Options >> tab Search Result Item Layout >> Item ordering >> Set to Most recent first. This setting will make all Result order by Most recent first.
Plus, when checking your site, we see another error with Pagination cause the HTML markup in your site is different with our demo, we also fixed it for you. Here is detail:
Go to file: modulesmod_jak2filterassetsjsjak2filter.js
find for:
if(!pages.length) {
pages = container.find('.k2Pagination ul li a');
}
change to:
if(!pages.length) {
pages = container.find('.pagination ul li a');
}
