AJAX function widgets disappear from screen

I have seen this post several times but no solution seems to work. When you set a filter the widgets section disappears. After refresh it appears again. I have tried changing homepage to current shop page, tried https://support.yithemes.com/hc/en-us/articles/115000934167-Ajax-Product-Filter-how-to-use-product-filter-without-ajax-filters-recharging-the-page- but nothing seems to give the right result. Any solution for me?
