I'm using PHP header re-directs to push my users through my PHP-HTML site, however I'm getting an unusual issue when attempting to do this.
The content displayed on-screen is not blank, but instead is the re-directed URL, however the URL bar still seems to show the old URL prior to re-directing.
There are no echo ""; statements, print_r(); statements or var_dump(); statements that could be causing this, nor is there any wild HTML or white-spaces (I've checked thrice, all HTML is encased in <<<HTML [htmlhere] HTML; and white-spaces have been eliminated using "Find & Replace")
I've also attempted to use exit(); after my header code to no assistance. Could anyone let me know if I'm being silly here?

$_SESSION['loc'] is being set in the main code (index.php) but, as that has no issue with re-directing, I'm not including it.
EDIT: header("Location: ".$_SESSION['loc'],true,301); (using a space after the colon) did not make a difference in the result
