詢問一個關於無法修改分類名的問題

剛安裝wp，修改後台分類是有問題了
% c- C5 L, W* {8 |5 q. [' lEdit Category
, f# l- \! h7 k" H" k( O

Name	The name is how it appears on your site.
Slug	The 「slug」 is the URL-friendly version of the name. It is usually all lowercase and contains only letters, numbers, and hyphens.
Parent	Categories, unlike tags, can have a hierarchy. You might have a Jazz category, and under that have children categories for Bebop and Big Band. Totally optional.
Description	The description is not prominent by default; however, some themes may show it.

+ t- s! D5 c% i$ Y3 Sslug 一行 這裡怎麼修改都沒反應，留空的話 就變成分類名後面加一個隨機數字，修改了保存不了是不是我的目錄權限不對？
4 F9 M2 k4 ?8 M/ }/ j% A$ D, R

; I% ~% D# f3 r: P9 p
3 j9 L- F; D  F( d

留空的話 就變成分類名後面加一個隨機數字，
$ d" B& J/ y/ `' z/ B
( A2 K: S! G! F7 k, b" {) f( t這數字不是隨機的.
: |7 n/ Q# R, h8 Y' s5 J3 b
3 P2 I) ]" z! c' J這數字是代表第n個相同term(tags, category, links, custom tax)名.

/ u- ?% H, A9 q要是理解了, 你就知道你問題的原因
