If you have been using the outstanding PopUpViewer on several versions of DokuWiki, like I have, upgrading to Kaos causes DokuWiki to fail showing the following error message

ArgumentCountError: 4 arguments are required, 2 given An unforeseen error has occured. This is most likely a bug somewhere. It might be a problem in the info plugin. More info has been written to the DokuWiki error log.

The issue seems to be caused by a more rigorous check in inc/Extension/PluginTrait.php of the information array in plugin.info.txt which should be included with every plugin. ¹⁾

For PopUpViewer, mandatory item desc is simply missing causing above error message which does not directly indicate what the root cause is, however. I fixed the issue by adding the mandatory desc item on the correct line.

Original

Fix

# General Plugin Info do not edit

base   popupviewer
author i-net software
email  tools@inetsoftware.de
date   2022-02-17
name   PopUpViewer
desc   Show a page in a popup window
url    https://github.com/i-net-software/dokuwiki-plugin-popupviewer

After this change, PopUpViewer will no longer halt DokuWiki version Kaos.
