Yahoo I solved it! It turns out that my wordpress database upgrade doesn’t successfully completed. I needed to force upgrade it using phpmyadmin > browse the wp_options table > look for the record whose “option_name” = “db_version” and set its value to “12329” (if your previous version is 2.9.2. if you have different source version then you should change this to that version’s corresponding db_version.
Then if you login again on the admin page it will ask you to upgrade your database. Just continue with the upgrade and you’ll be able to view the missing menus now. Enjoy ??
