index.php not showing/working in root folder

How are you redirecting it?

This way:

header("Location:page.php");

what error you got post your code and error type

the problem is when I type the url to the root folder of the website it shows a list of files in the folder and i dont want that so i placed this code in the index.php

<?php
header("Location:myMainHomepage.php");
?>

Have you tried adding a space after the colon? If that does not work either, try a fully qualified URL.

Tried both but still not working.
However it works on my localhost and even the index.php file doesn't show up in the root directory on the webserver.

Are you sure it's uploaded to the right location on your server then?

Yeah

be sure to turn on your error handling

<?php
error_reporting(E_ALL);
?>

you can also try

<?php
header("Location: http://www.yoursite.com/index.php");
?>

So, you're saying that http://www.example.com/index.php (your domain of course) when entered into the browser address bar, fails to show?

yeah, it fails to show up.
And browser shows the error : The resource requested could not be found on this server!
