Call to a member function setTreeNodeName() on null

I found this error while creating Express Object and when trying to upload files to File Manager

Please provide a fix.

We bumped into similar issue. If you have used phpMyAdmin to export the database dump and transferred it somewhere else, it can leave out some crucial database keys and column autoincrement information. Always prefer using the "mysqldump" command line tool.
