A quick update! The good operator Olga supposed a server cached related problem and she was right, sucuri firewall is saving a caches version of the staging site too (it shouldn’t because it has a different path for what I know).
I now can see all the costum work sorry for the mistake costumizer is working pretty well.
I just wait for this now:
after other costumization from another ticket I see that the One click purchase button near the add to cart one was moved from below to right, here as it was before (it’s old screen so don’t see the highligthed tags but the one click button instead of course):

I prefer to have it displayed in that way please, thanks you so much!
