This is an ongoing frustration... if I publish a post, then edit that post, the title "magically" disappears and is replaced with either the word "admin" or my user name (which seems to depend on how I've logged in). If I fail to notice it and remember change it back, when I update the post the title of it changes. I've looked through all the settings pages I can think of and find nothing that would cause this...
The blog I need help with is wboomsma.com.
