[Phpwiki-talk] Use of undefined constant RECENT_CHANGES

[Nick C. <ni...@ch...>]

In template 'head'(In template 'html'?):67: Notice[8]: Use of undefined 
constant RECENT_CHANGES - assumed 'RECENT_CHANGES':

    * <link rel="alternate" type="application/rss+xml" title="RSS"
      href="<?=WikiURL(RECENT_CHANGES, array('format' => 'rss'))?>" />

Any ideas?
