There are two kinds of links in Ektron.
Be sure to use Quicklinks
Place your cursor into the link. The hyperlink box will appear (if it does not appear, click anywhere in the content where there is not a link, then click within the link again). Edit the link.
To unlink text, place your cursor into the link. The hyperlink box will appear. Click the broken link icon to the right to remove the link (see below).
Note: If text is highlighted and the Insert Link icon is clicked, the text will appear to be a link, even if no URL has actually been entered. The best practice is to always check every link to make sure it's active and/or created properly
(watch out for links that begin with "http://http://").
