If a non-admin user tries to upload a document to a folder, they see error "Add document cannot be left blank". The document is being uploaded using a form and "Add document" is the name of the user input task. An admin user is able to successfully add the document without error. Checked the security access - the non-admin user has "author" access. Shouldn't author access be adequate? Any suggestions on what's missing?...
