How to Update Categories in WordPress

Sign into your blog
1. Sign into your WordPress blog by either using WordPress.com or your admin login. An admin login is required if WordPress has been installed directly on your server. For example, get a login page at www.yourdomain.com/wp-admin
2. Click on the 'Category' option located in the 'Posts' menu. After logging in, WordPress takes you to your blog's dashboard. On the left side of the screen are the menus.

3. Click on the category you want updated. To update categories, you have three options: Quick Edit, Edit and Delete. To update the category name or slug, the name that shows up in permalink, use Quick Edit. If you need to edit the Parent (the hierarchy it belongs in), or the description, you must use the Edit option.
4. Click on the 'Delete' option to permanently delete a category. Approve any prompts to confirm the deletion.
