Hello, The following error is shown at the page header when editing the sidebar namespace with the Argon template (the only content of the page is the AcMenu itself):

Warning: Trying to access array offset on value of type null in /home/robertinho/public_html/wiki/lib/plugins/acmenu/syntax.php on line 121

Hi, I've tested AcMenu plugin on the Argon template, on a new installation of DokuWiki (Release 2022-07-31a "Igor") with PHP Version 8.0.25.

I can edit the sidebar page without any warning (see screenshot). If you could give me more details so I can reproduce the issue, I will willingly take a look at it.

I have the display_errors PHP directive set to "On". I'm using PHP 8.1 and have the following content at my sidebar file:
