Comprehensive debug of every accordion form in Web Pages settings panel. Tested 12 AJAX endpoints across all accordion sections (Display Options, Menu Info, Metadata, Header, Sitemap, Security, Content, Video Embed gen+save, Get Started, Activate, Editable). Fixed: (1) update.menudetails.php — menu_meta_robot undefined array key, added ?? []. (2) add.submenu.php — fatal meta_tags no default, added required fields + siteid fallback. (3) update.menudetails.php — $logData/$menuDetailsData undefined before switch, initialized. Redis cache wrapped in try/catch. (4) update.menucontent.php — $menuid/$option/$configdata null guards. (5) modules/inc/ajax.php — $_POST[action] fallback, Redis try/catch. (6) display.php — replaced all $.Notification.notify() calls with swal() for v7 compatibility. Display Options checkboxes now show Settings Saved SweetAlert on toggle. All 12 endpoints return clean 200 with zero PHP errors.
