Hi all,
The file upload field of the Database activity causes errors in Moodle 2.3+. The drag and drop upload box in the field does not work and if users try to add entries through drag and drop anyway and submit the entry. This causes a database entry with NULL content. This empty entry in turn will break the list view of the Database activity (any entries after the empty entry become invisible).
The tracker issue is MDL-32456.
Rgrds,
Paul.
