Pages don’t show up in “Manage -> Pages” area

Hi,

I can create pages, I can view them in my browser (= they certainly exist) and even edit them, but the “Manage -> Pages” section says that I don’t have any pages.

On another installation I cannot provoke this behavior. Both are WP 1.5.1.2, use the same template “Mallow” and are in the same hosting enviroment. By deactivating all plugins one by one I tried to blame one of them, but it didn’t change anything.

Do you have any ideas?
