I just upgraded several of my websites that are running wordpress to WordPress 3.1. Now when I go to create new Post or Edit an old Post, several Post settings have disappeared on most of these websites but not all of them. I am running different themes for different websites. For example I am running the News theme by DevPress on one website. I do not see any problems in the post settings on that website. On another website I am running the wpFolio by wpfeed.com. When adding or editing a Post on the site, the Post Settings, Excerpt, Send Trackbacks, Customer Fields, Discussion, and Author sections are missing below the Post content area. There are several other websites that I am operating that are also having this problem.
