Hi,
Thanks for the access.
It looks like your HikaShop configuration was incorrect for the setting "Invoice order statuses".
This option lists the valid statuses indicating that an order is confirmed/paid/valid.
The previous setting had "bevestigd" instead of "confirmed" but the setting use the order statuses key.
In HikaShop 2.4.0 we improved the interface and now we use "namebox" to select the order statuses so there is no more confusion possible.

By the way, do not send me private message, use the "contact us" form instead.
