We learned first hand this problem when we moved a big clients site to wordpress. We found the email body was missing. After looking into it, we found the problem happening because data was being serialized in the database making it only work on the domain the data was created. Since then we were creating a backup of the email body before moving the sites.

Now this problem is gone, as all the data is saved as custom posts in the post table of wordpress, allowing us to not loss the data after site gets moved.

1) Upload to your hosting phpminadmin. This is a simple script that allows you to run a database query on your site allowing you to reset your password. You can download it from http://phpminiadmin.sourceforge.net/

2) You need to get database logins for your wordpress database. You can find them by viewing wp-config.php file. Values that are needed are in the following area:
/** The name of the database for WordPress */
define(‘DB_NAME’, ‘database-name-here‘);

/** MySQL database username */
define(‘DB_USER’, ‘database-user-here‘);

/** MySQL database password */
define(‘DB_PASSWORD’, ‘database-user-password-here‘);

/** MySQL hostname */
define(‘DB_HOST’, ‘localhost’);

3) Open the phpminiadmin file and update the values there in the following locations:
‘user’=>”database-user-here“,#required
‘pwd’=>”database-user-password-here“, #required
‘db’=>”database-name-here“, #default DB, optional
‘host’=>”",#optional

4) Upload phpminiadmin file to where you have your wordpress site is running.

5) Run the script and load the table called “wp_users”. Run the following query when you view the table:
UPDATE wp_users SET user_email= “youremail@yourdomain.com” WHERE user_login=”admin”

6) Now go to the login page on wordpress and click on “Lost your password?”. Put in your email address or user name. WordPress will send you a link to reset the password and you will be back in business.
