Reply To: The loading animation of the "add to cart" button would not stop.

After I updated the theme and the plug-ins as much as possible, the problem raised last time was solved, but new problems appeared.

After clicking the navigation bar cart icon, the items of the shopping cart slider that slides out from the right side can’t be deleted, and loading animation can’t stop.

I’ve already make the backup of the site. Could you help me settling this issue above? Thank you.
