In a space we are working on, lots of undefined page links have been set. Is there a way to see them all at once somewhere?
Yes, you can. You can see a list of all undefined pages in a space. Click on "Space tools’ at the bottom left of the sidebar, and then on “Content Tools”.
Select the “Undefined Pages” tab. All undefined page links will be displayed here so you can quickly see which pages are still waiting to be created.
Click on an undefined page link to create the page, enter its content, then “Publish” your new page.
