Child Terms not Displaying on the Taxonomy Term Admin Screen

I’ve encountered this kind of problem when i was building some front end post / term creation form. The number oh the ‘Right Now’ dashboard shows the right number of term, but the new term doesn’t shows up in the taxonomy admin screen.

The solution:

delete_option('taxonomy-name_children');

where ‘taxonomy-name’ is the name of the taxonomy.

Hope this help.
