We can definitely narrow this issue down. First, is this issue specific to file upload options? For example, can you add other types of Product Customizer options to your cart and / order orders?

  1. If this issue only occurs with file upload fields, please see how to use our NEW Ajax Mode to ensure a backup URL comes up on your orders here

  2. If all option types are missing from the cart and orders, please check out this document on missing options.
