Problems adding new post – page takes too long to load and times out

Hey there! Can someone look at the script on my wp-admin/post-new.php file and see if anything’s wonky? When I try to add a new post, I get a message saying the script is taking a long time to load and then Windows closes out on me. I’m running the latest version of WP.

<?php
/**
* New Post Administration Panel.
*
* @package WordPress
* @subpackage Administration
*/

/** Load WordPress Administration Bootstrap */
require_once(‘admin.php’);
$title = __(‘Add New Post’);
$parent_file = ‘edit.php’;
$editing = true;
wp_enqueue_script(‘autosave’);
wp_enqueue_script(‘post’);
if ( user_can_richedit() )
wp_enqueue_script(‘editor’);
add_thickbox();
wp_enqueue_script(‘media-upload’);
wp_enqueue_script(‘word-count’);

if ( ! current_user_can(‘edit_posts’) ) {
require_once (‘./admin-header.php’); ?>
<div class=”wrap”>
<p><?php printf(__(‘Since you’re a newcomer, you’ll have to wait for an admin to add the edit_posts capability to your user, in order to be authorized to post.
You can also e-mail the admin to ask for a promotion.
When you’re promoted, just reload this page and you’ll be able to blog. :)’), get_option(‘admin_email’)); ?>
</p>
</div>
<?php
include(‘admin-footer.php’);
exit();
}

// Show post form.
$post = get_default_post_to_edit();
include(‘edit-form-advanced.php’);

include(‘admin-footer.php’);
?>

Thanks so much!
