When building a site in WordPress, especially when setting up a custom taxonomy, its naming is very important. In many cases, custom taxonomy is used to build a site with its own classification, but you need to be careful about the naming of the taxonomy.
Why separate category names from custom taxonomy names?
For example, if a category “news” already exists, using the same name “news” when creating a new custom taxonomy will cause problems. Permanent link settings may conflict, resulting in a 404 error when accessing the category’s individual articles.
Solution.
The easiest way to avoid this is to add a prefix to the name of the custom taxonomy. For example, if you have a category called “news,” you can use a custom taxonomy name like “tax_news” to differentiate it.
Conclusion
When using custom taxonomies in WordPress, care should be taken not to use the same name as an existing category or post type. Having a proper naming convention will ensure that the links on your site work properly and avoid 404 errors.
