I’m having the frustrating situation as the beginning of this thread. Brand new WordPress install. Installed the latest Enlightenment theme from WordPress, was doing fine going through the home page tutorial, then noticed that when I created a third sidebar, it replaced the first, and so on. Came on this site and read through this thread.
Uninstalled the theme, checked that the folder was gone, then reinstalled from the zip linked in this thread. Noticed that the last three sidebars created were still there. Tried to add another. Same issue. Deleted all sidebars, uninstalled theme, reinstalled the theme from zip, created a sidebar. Now the second one I creates replaces the first, so I am stuck with just one sidebar. What is going on?
