I am experiencing this problem since Magento 2.2.5 and when upgrading to Magento 2.3 also. I use a custom template
Layered navigation with Ajax does not work. I'm using Amasty One
Just refresh the page and no product is called.
If I disable Ajax, everything is fine.
I can not give more details because I have no errors in the console nor in the log files.
I have two days now and I can not find anything.
Any help to check would be very appreciated
