Was the database working fine before? Have you followed the instructions on the wiki correctly?

Deprecated: Function mysql_list_tables() is deprecated in /home/jack019/public_html/vote.php on line 38

This means that the functions you are attempting to use are not supported in the latest version of PHP. x10Hosting uses PHP 5.3.x, so you will need to upgrade these scripts so it works with the latest version of PHP. There are usually many better alternatives available if a function becomes deprecated, so try searching for an alternative function.
