Page-level alerts are useful for fixing broken links or structural errors on the spot. If a page contains broken links and/or structural errors, admin users are immediately notified when viewing the page. Error notifications appear as page alert tabs in the lower right-hand corner of the browser window or as alert icons next to a broken link.
To display details about the page alert notification, click the page alert tab in the lower right-hand corner.
Click the linked text in the page alert tab to focus the browser on the broken link, now highlighted in red.
