On my individual product listing page the product images are blur but on the products category page the images are fine. I’m not sure why there is this problem and how to solve it.
They are blured because their size is to small. We suggest you increase sizes for product page images at least in two times (now its 400×600). Make it for example 800×1200 in WooCommerce -> Settings -> Products -> Display “Single Product Image”. And regenerate thumbnails after change.
