I don't know how to enable attachments.
When I go to Admin->Settings I only see these options:
System Preferences
Tickets
Emails
Knowledgebase
Autoresponder
Alerts & Notices
I have read http://www.openscriptsolution.com/ticket-system/osticket/how-to-setup-attachment-directory-in-osticket-system(http://www.openscriptsolution.com/ticket-system/osticket/how-to-setup-attachment-directory-in-osticket-system)
Am I missing another critical step?
