I get this Error: fatal error syntax error, unexpected 'is' (t_string) on line number 2
Sorry I am new at this. Everything was fine and not sure what changed Here is php code:

<?php
if (session_id() == "")
{
session_start();
}
if (session_id() == "")
{
session_start();
}
if (!isset($_SESSION['username']))
{
$_SESSION['referrer'] = $_SERVER['REQUEST_URI'];
header('Location: ./sorry.php');
exit;
}
if (isset($_SESSION['expires_by']))
{
$expires_by = intval($_SESSION['expires_by']);
if (time() < $expires_by)
{
$_SESSION['expires_by'] = time() + intval($_SESSION['expires_timeout']);
}
else
{
unset($_SESSION['username']);
unset($_SESSION['expires_by']);
unset($_SESSION['expires_timeout']);
$_SESSION['referrer'] = $_SERVER['REQUEST_URI'];
header('Location: ./sorry.php');
exit;
}
}
$roles = array("Administrator", "Member", "Guest");
if (!in_array($_SESSION['role'], $roles))
{
header('Location: ./sorry.php');
exit;
}
?>

I do not see any error in the code.
Are you sure this is the code that is causing the error?

No,

Just do not know where to look!

What is the code of the entire page?
Or do you have a demo project?
