Hi,
I'm having the same problem since I have updated to the latest version. Filters in the sidebar are not visible, but if I inspect the page using Chrome, I can see that they persist in the shop page and every single filter has a "display:none" style. I had like 10 filters, which are not visible after the update BUT there is only one filter I see in the sidebar - which shows me that the plugin is working, but the rest of the ajax filters are not "there", I mean visible. Its not a theme issue, because it's been 3 months since I have been using Extra theme by Elegantthemes and YITH WooCommerce Ajax Product Filter. I check everything, even made a complete working backup, updated the Yith Ajax Filter and the problem popped out again.I tried disabling every single plugin to debug the page - nothing changed. You can check the web page here:
Notice there is only 1 filter, despite I have all the filters in my Apperance tab in the admin panel. Any workaround or fix ?
