Why doesn't Magento Dhl-intraship create intraship shipments or documents?

Question

For some reason, the dhl intraship plugin does not seem to recognize when there are new orders. The cronjobs are running fine, but from what I could see in the code, they are always starting with intraship/shipment entities, but the corresponding table in my DB is empty, therefore the cronjobs do nothing.

How do I get the plugin to fill the table? Hopefully I could go from there and fix possible config problems.

My Magento Version is CE 1.7.0.2

I have no local overrides and no modifications in community/Dhl folder (I reinstalled and there were no changes in git)

Thanks! And sorry for the vague question, but I have no error messages whatsoever.

Answer 1

It appeared another module was listening to the sales_order_invoice_save_after event, creating a shipment and increasing the QtyShipped for orders right when the Invoice came in. Therefore the orders canShip() returned false when the intraship module ran the cronjob.
