<p>I have been to reproduce this bug on a plain setup, no other
cookbooks, default PMwiki skin. <br>
I don't have this message in PHP7.4</p>
<p>Line 39 in grouptitle.php has the following code<br>
</p>
<p><i> if ($page['title']) { return $page['title'];</i><br>
</p>
<p>I guessing a sintax update is needed, but not sure which one. I
realize this Cookbook is perhaps not the most used, but I would
appreciate some help to fix this issue. <br>
