Hey guys,
I saw that other people had the same problem with the size of the thumbnails on the product pages.
I don’t know if it is your theme or Visual Composer which resizes the uploaded images to a size of 86×109 px for thumbnails. Actually it is not WordPress because I typed other sizing for images in there. The thumbnails become extremely blurry this way. When you reduce the size of the browser window to a width of 767px the thumbnails are being displayed in the size of 697x891px and the theme or visual composer shows the 86x109px sized images so it is extremely blurry. I can’t find out where to change it. There is no possibility to do it through the Visual Composer Frontend and I didn’t find a solution in the Backend too.
Thank you in advance.
Benjamin
