I have installed a clean M2.2 webiste and tested with 1 product. Everything works fine.
After that I again created clean M2.2 isnatallation and did a migration form my old 1.9.2 store. Everything works great, all products, orders etc. are visible.
Except 1 thing the Ajax functionality stopped working. The Ajax Add To Cart stopped working.
I have tried all kinds of solutions. Cache, Compile etc. but no luck. Does anybody have an idea on how to troubleshoot this?
