If you are seeing blank products displayed in your storefront, it's because you have an active Shop Color with no designs with permission to display on it.
For example, if you selected White, Forest Green, and Navy as your shop colors, then uploaded a White logo, you may have chosen to Exclude that design from being displayed on white garments. However, your shop colors are still telling your store to display white garments -- just without designs!
If you choose to exclude your design from any garment colors you have selected as your shop colors, you’ll want to be sure to either add another design to display on excluded garment colors OR remove that color as a Shop Color by clicking Settings in the left navigation menu.
Once you enter your shop settings, you'll see all your selected Shop Colors displayed at the top of the page. To deselect a color, simply click on it & it will return to the list of unselected colors below.
