LS cache and AJAX on DIVI Woocommerce Extended

I have a problem. Using DIVI Woocommerce Extended. Works fine on every page, and after a while AJAX search and ajax apagination STOPS working. Just hangs.

They told me could be about LS cache. That is only thing different from other sites that i dont have problem.

Problem is its random, client calls and says SEARCH and pagination doesnt work.

THEN i try on my mobile, dekstop it works fine. Then other time reversed, for me it doesnt work.

In error log i only see:
