Order number not displaying

Thanks for your really prompt responses.

The order numbers are not appearing anywhere, not in order, confirmation or sales history.

Please advise.

Which version of HikaShop are you using ?

I'm using the latest Starter version.

It's a bug introduced in the version of yesterday. We packaged a new version with the problem corrected.
Pleas download again the new install package and install it via the joomla installer.
That should fix the problem automatically for new orders.

Thanks!
