You are getting this error because you are already outputting content before setting a header.
If your include("delete.php"); is going to redirect then you will need to perform this before outputting content.
try...
// before any output
if(!isset($_SESSION['admin_email']) && isset($_GET['delete'])){
include("delete.php");
}
?>
<div id="wrapper">
<?php include("includes/sidebar.php"); ?>
<div id="page-wrapper">
<div class="container-fluid">
<?php
if(isset($_GET['dashboard'])){
include("dashboard.php");
}
if(isset($_GET['view'])){
include("view.php");
}
if(isset($_GET['delete'])){
// remove this from delete.php
if(!isset($_SESSION['admin_email'])){
// looking at it, this may also want to be at the top
// if you are checking for a 'logged in user'
echo "<script>window.open('login.php','_self')</script>";
}
}
