Hello, we have a problem with the plugin. At first it worked perfectly. Now it does not show the layout of the product. It shows the initializing loader continuously (as in capture 1). We think it is the setting UI LAYOUT, we see that it is empty (as in capture 2). We can not edit or revert to default because it does not save anything.
More likely a server or conflict issue. Please open a support ticket and send links and credentials to your wp-admin so that we can take a look.
