Hello there,
Turning off that revealed that there’s CSS that’s causing the issues you’re facing.
It looks like the box is being caused by:
.wc-block-grid__product-add-to-cart.wp-block-button .wp-block-button__link.added::after {
content: "";
display: inline-block;
font-family: WooCommerce;
height: auto;
margin-left: 0.5em;
width: auto;
}
The S’s are being caused by:
.wc-block-grid__product-rating .star-rating span:before, .wc-block-grid__product-rating .wc-block-grid__product-rating__stars span:before {
color: inherit;
content: "SSSSS";
left: 0;
position: absolute;
right: 0;
top: 0;
white-space: nowrap;
}
The CSS is being loaded by this file: https://c0.wp.com/p/woocommerce/8.8.2/assets/client/blocks/wc-blocks.css
Is the performance setting still active as above? If not, if you were to turn this off, and clear the sites cache, does this resolve?
I hope this extra insight is useful!
