I upgraded my DokuWiki instance to PHP 8.1 (PHP 7.4 is deprecated now) and the following errors are being shown at the top of my Wiki:
Warning: Trying to access array offset on value of type null in /home/robertinho/public_html/wiki/lib/plugins/epub/action.php on line 104
Warning: Cannot modify header information - headers already sent by (output started at /home/robertinho/public_html/wiki/lib/plugins/dw2pdf/action.php:914) in /home/robertinho/public_html/wiki/inc/actions.php on line 38
Disabling the plug-in fixes the issue.
Please let me know if there's any information I can provide to troubleshoot and fix this issue.
