Controller or its method is not found: \App\Controllers\Tasks::index

@kenjis 
also used current version using official guide Composer Installation but failed to get it.
will check "spark serve", not yet tested because the controller Home.php is showing the page as expected but Tasks.php not.
will give you feedback.
regards

no, the same error message appears after "php spark serve" and enter in browser
http://localhost:8080/tasks

while http://localhost:8080 is showing home page and this too: http://localhost:8080/home
