Problems migrating servers – saved backed has problematic files

Try:
– switching to the Twenty Ten theme by renaming your current theme’s folder in wp-content/themes using FTP or whatever file management application your host provides.

– resetting the plugins folder by FTP or phpMyAdmin.

– renaming any .htaccess files.

Thanks!

(1)I have the Twenty Ten theme in my folder already. Can you explain then what I would do? Delete the other themes?

(2)I don’t think I can try the resetting the plugins options because I don’thave access to the WP Admin:

Create an empty plugins folder
Via FTP or your host’s control panel, navigate to the wp-contents folder (directory)
Via FTP or your host’s control panel, rename the folder “plugins” to “plugins.hold”
Via FTP or your host’s control panel, create new folder called “plugins”
Login to your WordPress administration menus
Via FTP or your host’s control panel, delete the empty “plugins” you previous created
Via FTP or your host’s control panel, rename “plugins.hold” back to “plugins”

(3)And I would need to rename any .htaccess files to what exactly?

I tried re-loading the WP-content folder and see this when I go to my site:

<?php
/**
* 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-header.php’);
?>

I see this now, when I go to the subdomain where I deleted and then reloaded the wp-content folder:

<?php
/**
* 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-header.php’);
?>

Individual posts show, however the homepage still shows the script above.
