Reply To: Wishlist does not work

Hello,
I admit it looks like a cache problem, but I tried it in 2 different browsers on 2 different computers, and on my side it is not working at all. The behaviour is always different but never working correctly. I created another staging, deactivated all 3rd plugins there, no caching plugin running, deleted all caches in the browser, but the same problems, see video. Below the login for the new staging.
Best regards
