Filter button is not working anymore

Hello and thank you for your plugin, very useful, I have been using it for two years now. I consider buying premium version soon.

However, it is not working anymore since a recent update. In front-end, filter button is not working, filtering is not loading at all when I click on it. In the back-end, everything seems to work fine. I didn’t change anything recently, it was working fine until now. I cleared cache, saved again plugin options, but it is still not working. Could you help please ?

Thank you very much and have a nice day
