MySQL problem(s)

[gesf]

Any errors !? Put the following code at the very top of your site/page:

<?php error_reporting(E_ALL); ?>

Now you'll know about what's going on!
Post the errors you get after.

Do you have a database backup ? I hope you do

For database clients like PhpMyAdmin you can easily import the backup file, and again, create and populate the tables.
You can also do it through the mysql command line:
For an entire database:

> mysqldump --all database_name > dump.txt

And then on your new database server:

> mysqladmin create database_name
> mysql database_name < dump.txt
