Hi Jon,

Thanks for your feedback.

We have LabKey release18.3 and indeed that happens with folders from all projects. The fact is that only site admins can delete folders. When a user creates a folder and immediately tries to delete it without having populated it, deletion also fails, with the same reported error.

That is not happening in our dev LabKey 19.1 instance though.
So, we will upgrade and and check if the issue has been solved.

Best regards,
Eva
