I have a site with 1 post in it, assigned to a category called Ultra. When you click on the category in the menu (all categories were assigned to the main menu), it does not acknowledge that there are any posts in that category. I have tried to remove all plugins, change to the default theme, etc. . . and it keeps doing this.
You can see the problem here: http://www.runlivelearn.com
I run 3 other wordpress sites on this server and none of them have had any problem with this, so I'm pretty confused. Any help would be appreciated.
