They all are there, and all have auto_increment.
As mentioned, it works fine when I add new category. The wrong thing just happen when I add a sub-category.
1. When add new category:
everything OK
2.When Add Sub-category to the old category (the one already exist in my old data)(I just update my WordPress from 2.1 to 2.3):
everything OK
3. When add sub-category to the new category (the one I add after upgrade from 2.1 to 2.3)
a. Add okie
b. After refresh, the new added sub-category disappear (in the manage panel)
c. When check in the database, the new added sub-category is there,
==> the only trouble is that, it disappear after refresh, and never come up again in the manage panel
Thanks, the plug-in itself works
But it is not the file in your links, it damaged. Another link: http://wp-plugins.net/
