Hi, I am getting a lot of errors like this

2024-02-28 17:42:39 E_WARNING: Trying to access array offset on value of type null /var/www/html/lib/plugins/indexmenu/syntax/indexmenu.php(842) #0 /var/www/html/lib/plugins/indexmenu/syntax/indexmenu.php(842): dokuwiki\ErrorHandler::errorHandler(2, '...', '...', 842) #1 /var/www/html/inc/html.php(500): syntax_plugin_indexmenu_indexmenu->formatIndexmenuItem(Array) #2 /var/www/html/lib/plugins/indexmenu/syntax/indexmenu.php(544): html_buildlist(Array, '...', Array, Array) #3 /var/www/html/lib/plugins/indexmenu/syntax/indexmenu.php(531): syntax_plugin_indexmenu_indexmenu->buildNoJSTree(Array, '...', '...') #4 /var/www/html/lib/plugins/indexmenu/syntax/indexmenu.php(466): syntax_plugin_indexmenu_indexmenu->buildHtmlIndexmenu('...', Array, Array, Array, 1) #5 /var/www/html/lib/plugins/text/renderer.php(45): syntax_plugin_indexmenu_indexmenu->render('...', Object(renderer_plugin_text), Array) #6 /var/www/html/inc/parserutils.php(691): renderer_plugin_text->plugin('...', Array, 5, '...') #7 /var/www/html/inc/parserutils.php(158): p_render('...', Array, NULL) #8 /var/www/html/lib/plugins/searchtext/action.php(34): p_cached_output('...', '...') #9 /var/www/html/inc/Extension/EventHandler.php(80): action_plugin_searchtext->_getSearch(Object(dokuwiki\Extension\Event), NULL) #10 /var/www/html/inc/Extension/Event.php(75): dokuwiki\Extension\EventHandler->process_event(Object(dokuwiki\Extension\Event), '...') #11 /var/www/html/inc/indexer.php(189): dokuwiki\Extension\Event->advise_before() #12 /var/www/html/inc/TaskRunner.php(206): idx_addPage('...', true) #13 /var/www/html/inc/TaskRunner.php(52): dokuwiki\TaskRunner->runIndexer() #14 /var/www/html/lib/exe/taskrunner.php(20): dokuwiki\TaskRunner->run() #15 {main}
What could be the reason. Using the old indexmenu syntax.

Ok, seems like the issue was with dokuwiki itself. There is a newer version (kaps 2024-02-06a) which fixes the problem

Ok, perfect. Otherwise you may reopen it again.
