Spinner in the Detail Page Unero2

To fix this problem, please go to MGS -> Theme Settings -> Custom Style ( maybe you will must select store view you are using) then add this code to Custom Style

.product-info-main-content .product.media:after {
    content: none;
}

then Save Config, refresh cache and check again! In some case, if you don't see changes, maybe your server's cache is on, so you need to refresh server's cache.
