I am unable to create subitems on the menu. The problem is new: I tried to add a new page under a parent page two days ago, and after saving the menu, the sub item jumps back the original position and appears as a main menu item, even though the page attributes clearly show the one or two dashes indicating placement, and the "add to menu" column on the left also shows the hierarchy of the pages. I deleted the entire menu and started over, same result. I also cleared the browser cache and cookies.
The blog I need help with is theharringtonreview.com.
