DB Error 1054 and no Departments on new install

Just installed osTicket for the first time.

Under Departments, it shows "Query returned 0 results", even though both default Support and Billing departments are visible in other menus.

Also, everytime I access the Departments tab in the admin menu, and possibly other times, I get a DB Error 1054 with:

Unknown column ' ' in 'field list'

Thanks in advance for any suggestions!

try re-uploading your files, sounds like something may be corrupted.
