There are still no widgets here. To add some content please go to the Dashboard and add some Widgets to the Top Sidebar. If you don't need this section just go to Mercina Options and switch off the Top Sidebar.
Something is missing... The Slideshow Module is active, but there are no slides. Go to the Slides section and Add a New Slide. If you don't need this module on the homepage at all go to the Mercina Theme Options page and disable it on the Homepage Tab.
