- Renamed AdminController to PageController
- Route name is 'page#index' so controller must be 'PageController'
- Fixes Could not resolve PageController error
- Updated routes.php to use PageController
- Updated info.xml navigation to point to PageController
- Removed old AdminController.php
- Improved HTML output with better styling and next steps
This was the root cause: Controller class name must match route name.
Route: page#index → Controller: PageController
App routing should now work correctly!
