Just something weird I have come across in WordPress while trying to create a static page called "About" with the url sitename.co.nz/wordpress/about. I created this page called About and tried to make the URL "wordpress/about/". I can edit the url fine and call it "about" but when I click update, wordpress renames it to about-2 or sometimes about-3.
Any ideas about this? At first I thought it was because I had old page called "About" in the trash, which I deleted then created a new page, but that hasn't helped.
EDIT: Following this, when I rename it to something like "aboutpage" nothing is changed and it works how it should.
