Demo Import missing fields
According to demo import documentation, in order to import demo data you have to access our demo admin page.
For example, if you are interested in demo 5, access journal-theme.com/5/admin using username demo and password demo and then export the demo data from Journal > System > Import / Export.
Usually, if you don't see the ThemeForest User and Purchase Code fields, then you are probably accessing your own admin page and not the demo admin page on our domain.
