Invalid parent ID

Hi,
we use batch upload to send our files to the server.
after upload the files we click "next step"
Then edocman shows "Invalid parent ID." Error Message on white screen.

What can we do? The problem should be since update to latest version of edocman.
Re-Install Joomla core and edocman (latest version) already done, but the problem is the same.
Joomla said "Database ok" - No Errors found.

We use latest version from edocman under Joomla 5.4.3

Hi Tobias,
Could you please submit ticket on category Edocman and provide your site credentials so i can check the issue for you.
Thanks
Dam
