Hello,

1. I have deactivated all the plugins and switched to the parent theme https://gyazo.com/d7bfa900de69f0506690efe2e34e3230

2. I have activated the required plugin http://prntscr.com/nz703d

I am checking the site now I cannot find:

a) all show pixelated when I upload them on the site

b) I have created and saved a testing product and it is not shown twice http://prntscr.com/nz71l6 I have added a price, saved and it is not duplicated.

Our theme is fully compatible with Woocommerce and works smoothly with this plugin. As for the rest plugins we do not guarantee, please activate the plugins one by one, to detect which one causes the problem and contact this plugin support or replace for an equivalent.

Best Regards
