How Do I Delete A Pretty Plugin Category


Not sure why, but when creating categories for plugins, after creating one and then moving to another plugin then when selecting a category, some previously created categories do not appear.

When I create the same category again for the new plugin, then later the category appears twice in the list of plugin categories.

Since this quirk may be a plugin conflict, I am not as concerned about that happening as I am about knowing how to delete categories that are not needed or that happen to get created in duplicate.

Does deleting plugin categories require manually editing the database?

Please advise.
