One-Page Checkout [Support Thread]

[suportafaceri]

Hello, I have installed the plugin and I have a problem, I sell virtual products so no shipping is required, it doesn't show a shipping method or shipping information (that is as it should) but It doesn't let me confirm the order as a message appears „You must choose a shipping method for your order.....
Test site - Zencart 1.5.5a with only Ceon-URI-Mapping-4.5.2 installed.
This is the error logged message (i checked and the files exist):
