A second condition is that the page must be small to be deleted. Only when the PageSize also below a limit (64 characters are configured as default in Option/DeletePageLimit) the "delete page" link is displayed.

So, to delete a page you

1. (make sure to have entered a user name)
2. remove the page content by editing and storing.
3. click the link "delete page" at the bottom of the page

• PageDeletion -- general information about the feature
• Option/DeletePageLimit -- change the limit that defines "small enough for deletion"
• Command/ActionDelete -- the command that actually implements this (of course you can also enter the command directly)

Hint: If you have to delete a lot of pages for some reasons, you can set the DeletePageLimit e. g. to a zillion characters then every page becomes directly deletable. This saves a lot of time but don't forget to restore the limit to the lower default value afterwards.
