you are starting session multiple times, it is needed only once. — , Sep 07 '16 at 12:27
Where do you set a value into the `$_SESSION['username']` as I cannot see anywhere in the code you shows us — RiggsFolly, Sep 07 '16 at 12:34

Replace all session_start() with the following check:

if (session_status() == PHP_SESSION_NONE) {
    session_start();
}

Cannot think why this would fix anything – RiggsFolly Sep 07 '16 at 12:32
Might be more useful to ask where does OP set a value into the `$_SESSION['username']` as I cannot see anywhere in the code he shows us – RiggsFolly Sep 07 '16 at 12:33

try this,

in check.php

Replace session_start(); with this code

if(!isset($_SESSION)) 
{ 
    session_start(); 
}

I suggest you to use ob_start(); before starting any sesson varriable.
