Property Stock->physical_quantity is not valid

['Woger]

When I try to set a specific order to sent I get this error:

[PrestaShopException]

Property Stock->physical_quantity is not valid

  How do I debug this? I found in an older post that it has something to do with the stock. I have set the amount to advanced and manually for all the included items.
  Prestashop is version 1.6.0.11
   
  Thanks,

You have found a solution?

Here also,

Can't figure out the problem. Can't change the status to anything else.

Hold on.

If I turn off advanced stock management for a specific item, it works.
