The last few months, unfortunately, uploading to the back of products at MBA has not worked properly. Now it should work again.

You can now enable the “Back” option for individual products in your templates.
Or all those who want to decide individually per design, there are as “CustomArg” in the tables now following options:
* back – all designs will be placed on the back side.
* back_productName – the design will be placed on the back of a named product. the product name must be written lower case and spaces must be replaced with a hyphen. For example: back_standard-t-shirt

This has been updated accordingly in our documentation:
