Login to the back-end if you haven't already.
- Go to Menu Manager.
- Click Rebuild (this step may not be essential, but it does no harm).
- Go to Content > Categories.
- Click Rebuild.
- Create a New Category called Temp
- Batch move all your categories to the new Category.
- Batch move all categories back to the /Root directory.
If you have nested categories, you'll have to move them back into their respective sub-categories.
