the folder 'mvc' in wwwroot of my local webserver is working perfectly fine.
i have re-checked the points you mentioned
i haven't missed any of the configurations in CI, i know that CI i.e index.php is working well , even the files are uploaded properly.
major point to note: that the same configrations are working well on my localhost.
even i am confused why this is happening?
