Demonstration (for `#c0`)

SUMMARY
-------

`api.kde.org` links to a non-existent bug tracker in its footer, instead of this Bugzilla instance.

STEPS TO REPRODUCE
------------------

Visit [`api.kde.org/legacy/4.12-api/kdelibs-apidocs/kdeui/html/classQTreeWidget.html`][1].

OBSERVED RESULT
---------------

It links to a 404 URI (instead of `bugs.kde.org`):

> ~~~HTML
> <div id="footer_text">
>     Report problems with this website to <a href="http://sysadmin.kde.org/tickets/">our bug tracking system</a>.<br>
>     Contact the specific authors with questions and comments about the page contents.<p>
>     KDE<sup>®</sup> and <a href="/media/images/kde_gear_black.png">the K Desktop Environment<sup>®</sup> logo</a> are registered trademarks of <a href="http://ev.kde.org/" title="Homepage of the KDE non-profit Organization">KDE e.V.</a> |
>         <a href="http://www.kde.org/contact/impressum.php">Legal</a></p>
>     </div>
> ~~~

EXPECTED RESULT
---------------

It should link here, I presume:

~~~diff
  <div id="footer_text">
-     Report problems with this website to <a href="http://sysadmin.kde.org/tickets/">our bug tracking system</a>.<br>
+     Report problems with this website to <a href="https://bugs.kde.org/enter_bug.cgi?classification=Websites">our bug tracking system</a>.<br>
      Contact the specific authors with questions and comments about the page contents.<p>
