How to Prevent Your Links from Breaking
This How-to applies to: 2.5
Let's say you have a link on one of your pages that points to a .pdf file. If that file happens to get moved to a different folder on your site, the link between the page and file would break. Kupu now offers a way to prevent this from happening.

Click on the Site Setup link. You should now see a screen that looks something like this:

Look for the Kupu visual editor (the one with the butterfly) and click
on it. Now make sure that the Link using UIDs box is checked. You can also enable captioned images from here. Be sure to push Save at the bottom of the
page, when you're done.
