I used the one-click install in Dreamhost to upgrade WordPress from 2.2.1 to 2.3.3. The files seem to be up-to-date on the FTP. Dreamhost indicates that WordPress is updated, but when I'm logged into WordPress it still reads at the bottom of the page that I'm using 2.2.1 (and the added function of 2.3.3 are missing) Any suggestions on what to try next?
