The only widget area that seems to be working fine for me is the sidebar and footer widget. Anything I add or delete works smoothly. The problem comes in when I add anything to the Left / Right sidebar widget area, header, grid or content widget area. Nothing shows up.
Further, when I add my pages in the Footer area then there is a long list of pages in one column. How can I limit the number of pages in one column to 10 and the remaining in additional column, and how can I include only certain pages and not all the pages
