We have a production website https://www.nabalifairkost.com/ with Freshio theme Version: 1.9.2 and we wanted to update it to the latest version, so we created a staging website (where all the work should be done) https://staging-wptechsupport.com/nabalifairkost/
We updated the theme to version 2.2.1 and some of product images got blurry.
You can see those images on link:
https://staging-wptechsupport.com/nabalifairkost/en/produkt-kategorie/gewuerze/page/3/
and you can take this product as an example:
https://staging-wptechsupport.com/nabalifairkost/en/produkt/gewuerze-quartett/
wptech footer – final
Check those products on some category pages where they fall into and you will see that on the old version, images are showing fine (production website), but on the new theme version (staging website), images are blurry.
I repeat, if you check those products on their single product page, they are fine, but when you check them on the product category page, that’s where they become blurry.
