@magento 1.9 whenever I go to Sales>Shipment I get these errors. I've tried to edit some files but couldn't get any step further. The webshop is live for a month or 3 now, and since a couple a days I get this error when I need to send my order, I can't. This is really annoying due the customers that are waiting.
I have no idea which file I need to edit, or what I need to delete to dismiss this error. Already googled the error, but can't see any similair to this one, because I didn't edit any code for this to happen.
Please,
