when you move a website, and you just copy over the database as is, the website won't work properly.
because it contains your previous website's domain name and many urls pointing to that previous website.
you need to do a search and replace on the sql file before importing it to your phpmyadmin on your new webhost
many cloning/moving plugins do this for you
