@Ismael: Thanks, it works :)
(Setting the ‘Product thumbnails‘-size to 450x450px)

I didn’t change it before, because I was so focused on the ‘Single product image’-setting..
And, I don’t really understand that ‘Product thumbnails’-size setting affects the ‘Singel product image’.. But I guess that’s a question for woocommerce…

I’m happy you guys helped me out :) Thanks again!!!

I have same problem, also in Firefox. I’ve regenerated thumbnails + cleared cache, but problem persists..:

(right click the broken picture link + show picture..)

Hi Andy, I sent the logins to my page: Please go to the webshop and click a random product. Then you’ll see the problem.. Thanks.

Hi there,

I had/ have the same problem: The one with the ‘big words’ was fixed by changing a setting in the childtheme, but I’m having NO SUCCESS in fixing the single product images, which are super-blurry…
The problem was just there one day, never had this problem before, and my webshop has been online for 1 year.. I’ve done all the setting size of product image + regenerating thumbnails, and now I also tried to re-upload a productimage just to see if that had an effect. It didn’t. Still very blurry…. My site is in maintenance… But I’d really like to get back online ASAP .. Please help.
