I can’t do a reinstall. I have weveral years of posts, and this is my company page. I think this must be the section of code from upgrade.php that is causing my problem. Any advice on how I can modify it to let me back in? I’m not a programmer.

?>
<?php else :
switch ( $step ) :
	case 0:
		$goback = stripslashes( wp_get_referer() );
		$goback = esc_url_raw( $goback );
		$goback = urlencode( $goback );
?>
<h2><?php _e( 'Database Update Required' ); ?></h2>
<p><?php _e( 'WordPress has been updated! Before we send you on your way, we have to update your database to the newest version.' ); ?></p>
<p><?php _e( 'The update process may take a little while, so please be patient.' ); ?></p>
<p class="step"><a>"><?php _e( 'Update WordPress Database' ); ?></a></p>
<?php
		break;
	case 1:
		wp_upgrade();

			$backto = !empty($_GET['backto']) ? stripslashes( urldecode( $_GET['backto'] ) ) : __get_option( 'home' ) . '/';
			$backto = esc_url( $backto );
			$backto = wp_validate_redirect($backto, __get_option( 'home' ) . '/');
?>

Okay, I now know that the issue which causes me to be locked out is the table prefix line in the wp-config file. When that’s set to the default _WP, it thinks this is a brand new site and completes the update for me. And my entire web site disappears. When it’s set to the real table prefix it locks me into the loop again.

Where can I go from here?

Okay, where would I get a better version of those files to overwrite?
