I've installed the Nucleus theme and Neris sub-theme on new Drupal 7 deployment, with just Main Content (Main Page Content), Help (System Help) and Sidebar First (Navigation, User Login, Management). Essentially the Drupal Basic install profile.
And on my frontpage - Neris throws my Main Content off to the right. See image.
I'd like to be able to build my Modules manually, so aren't interested in the Installation Profile. But could you advise what's happening here, and what I need to do to resolve it?
