If you haven’t selected a category when publishing a post in WordPress, WordPress automatically assigns it to the default category.
If you haven’t changed your default category in WordPress, it will go to a category called Uncategorized.
To change your default category, go to Posts > Categories.
If you do not have a default category, a category that you wish all your posts to go into when you don’t select the category manually, add it here.
- Category > Add New
- Type in the category name with proper spelling and capitalization
- Type in a category description
- Click Add New Category
If you hover over the Uncategorized category in the Categories screen, you will see that you can’t delete it. WordPress automatically protects the default category.
To change the default category:
- Go to Settings > Writing
- Change the Default Post Category to the new one you just created
- Click Save
Return to the Categories screen and you will see that the category you just created cannot now be deleted. And the Uncategorized category maybe deleted. Delete it and your worries will be over.
