file upload problem, error code 200

Hi
I need some “kick in the right direction” from the all knowing wix community for an error message I can not understand.
I have a very simple form where I have som input text boxes and an upload button for documents. When selecting a file pressing my submit button I get the following error:

What I’ve tried so far:

  • the permission in the db is set to permit “everything for everyone”
  • tried (and succeeded) to upload a file to the db from the db interface
  • tried different type of files and file names
  • other input textboxes get submitted to the db successfully, but as soon as I try to add a file, I get the above error msg.
  • file type is set to document, (both in dataset and in db)

help?

Answering my own issue. After a logout and login to wix, the issue sorted itself. Now I have another issue, but atleast some progress.
