I want to exclude certain categories from appearing in the category cloud.
There’s an option for this, but it seems to be broken – the categories I list to be excluded are still included. (Blurb, Uncategorized)
Is this widget broken?
Is category ID simply the name of the category (eg Uncategorized) or is it something else?
The option isn’t broken: category IDs are numbers. To find the ID of a category, you go to Posts > Categories: hover over the name and look at the status/progress bar of your browser, or hover over the name then click Edit and look at the address bar of your browser.
