[Plugin: WooCommerce] product image blurry

Hi,

I have updated WordPress and WooCommerce to the latest version and am having trouble with the product feature image – which resizes to 300 x 300 even after I changed the settings on both Woo – Display, and WP – Settings – Media, where I then regenerated the thumbnails. However, this does not seem to make a difference. I am using ‘Sensational’ by MyThemeShop. Also, I thought I should note that both images larger than 300 x 300 and those smaller than 300 x 300 are blurry, and I have absolutely no idea why. In addition, the thumbnails (on the category page and for related products) also seem to be blurry. Other images on the site are totally fine, but the WooCommerce ones are displaying these issues.

Any help would be highly appreciated!

Thanks
