*Please enter the Administration Section of the Content General to complete setup.*
You must select Display Categories and Category Permissions to be able to add items. There is one default category called "General". If you plan to have more categories, you must create them before entering the Administration section.
Also, keep in mind that if you activate features, they will not show up in the "Add New Item" admin until the token is added to a template. Some tokens (The FLV player token, [VIDEO], for example) are not included in the default template. You must add those tokens on your own before you can use those features.
