Hi <br>
<div>
<p>I have been testing the latest Pmwiki 2.3.2 on PHP8.0 I have
the following warning message:</p>
</div>
<p><b style="color:rgb(0,0,0);font-family:Arial,Helvetica,sans-serif;font-size:14.6667px;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;text-decoration-style:initial;text-decoration-color:initial">Warning</b><span style="color:rgb(0,0,0);font-family:Arial,Helvetica,sans-serif;font-size:14.6667px;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;background-color:rgb(247,247,247);text-decoration-style:initial;text-decoration-color:initial;display:inline;float:none">: Undefined array key "title" in<span>

<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>
</p>
