It looks like you set the URL (during setup) to "localhost", rather than the correct URL.
Go to Admin Panel → Server Settings and make sure the correct URL is set. Then, go to Admin Panel → Themes and Layout → Themes and Settings, check the URL at the bottom of the page is correct, and click on "Attempt to reset all themes".
If you have any further problems, please make a seperate topic for them (it's not really related to this topic

)
