Hello,

1. How can we reproduce the error and see this message on your website?

2. Try to use the following CSS code

.wrapper-full-width-content .container {
		max-width:1900px
} 

3.

.post-head:hover img {
    transform: scale3d(1.1,1.1,1);
    -webkit-transform: scale3d(1.1,1.1,1);
}

.post-head .entry-thumbnail {
	overflow:hidden;
}

.post-head img {
    display: block;
    margin: -1px;
    -webkit-transition: transform .5s cubic-bezier(0,0,.44,1.18);
    -webkit-transition: -webkit-transform .5s cubic-bezier(0,0,.44,1.18);
    transition: -webkit-transform .5s cubic-bezier(0,0,.44,1.18);
    transition: transform .5s cubic-bezier(0,0,.44,1.18);
    transition: transform .5s cubic-bezier(0,0,.44,1.18),-webkit-transform .5s cubic-bezier(0,0,.44,1.18);
}

4. Add this for mobile and tablet devices

.woocommerce .shop_table td.product-thumbnail img {
    max-width: 248px!important;
}

.woocommerce .shop_table_responsive tbody td:before {
    display:none;
}

.woocommerce .shop_table.cart tbody td {
	text-align:center;
	padding:5px;
}

5. a. It should be found in our theme PO file. Could you please provide us your admin access so we can check?

b. This is related to WooCommerce plugin.
