Help me please

I try to install dolphin7 and installation complete. But problems are I found only People, Tag, Categories, Search, About and Help. I can not see Forum, Ads or other tab like I see in demo site.

Could anyone help me?

Thank

Unlike in Dolphin 6.1.6, Dolphin 7.0 takes advantage of modules far more, and most features can now be enabled or disabled with the click of a button.

The modules you are looking for are no longer installed by default, but you can easily do so. Navigate to Admin > Tools > Modules and install the modules you wish to use with Dolphin. Note, that some modules rely on others, so some must be installed together.
