Hi, i'm in trouble with the migration of prestashop from local (wamp) to server. My problem is that after I change color or size, it disappear. It seems that some javascript is not executed (i don't know if it's important i'm a newbie). I don't have this problem in local and there is not error in console javascript and not even in php error log. I've already tried to set default theme but the problem still there. It seems to be a problem of core.js file in theme folder. If you wanna try, this is the url https://b2b.florence-bags.com/it/borse/47-207-borsa-alas-0312.html#/2-dimensione-m/5-colore-grigio . I attach prestashop info.
