Hello @anton,
I have just tested your site and the search functionality appears to be working correctly. I have recorded a video of the site, which you can view here: https://www.veed.io/view/2816b412-6f16-4b6c-a486-e18c5189e154?sharingWidget=true&panel=share.
It is likely a caching issue on your end, so please try clearing your cache and testing again.
Best Regards, 8Theme’s Team
