“I’m Knight” provided some valuable insights on the reorganization of categories and tags under WordPress
Why reorganize?
- consolidate into fewer categories and make it one level only. No more hierarchy category.
- the tag feature is build-in now. I can just make a open source category and tag each entry with more specific tag like Debian and LAMP.
- tag your old post too, make it more visible to the search engine
- tags can sort out the related posts and help display them to visitors
Tools to use
When I tried to change category names, WordPress simply prompted “category not updated”. I digged into the WordPress forum and find the solution in this post.
The issue may be that you are trying to change a category slug description to a category slug description that already exists within your blog. No doubles are allowed.
I changed the category slug into a unique one and the problem was resolved.
Or better, instead of changing the slug or category, deleting the conflicting tags seems to be a better solution:
This happen after wordpress 2.3 release and introduce tag feature , the database structure has been changed, it combine the links category, post category and tag in one table, because for category slug it need to be unique, when you unable to change means the “word” has been used either by link category or tag.
