After login, all post's are filed under now uncategorized I tried to create a category and WP says, category already exists. I tried to select a category for post but it does not work. It happening only when I logged in at WP admin and for every blog in my network. Also, just updated with WP 2.7 to recover this but still problem exists. Anybody can recognize this issue??? One of my blog: http://www.esportslog.com EDIT: Blog Roll is not showing anymore! Thanks in advance.
