Path is wrong!

I recently moved my WordPress to a new host from 1and1. It all comes up fine, but in the header, there is a error message that reads

Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/homepages/46/d119326795/htdocs//wp-content/uploads) is not within the allowed path(s): (/tmp:/usr/share/pear:/home/fhlinux172/m/maxblog.co.uk/user) in /home/fhlinux172/m/maxblog.co.uk/user/htdocs/site/wp-content/plugins/podpress/podpress_class.php on line 160

What gets me is that /homepages/46/d119326795/htdocs//wp-content/uploads is the path of my old host, and the one after is the new one. Is this stored somewhere? Do I need to change it?

Thanks in advance,
Max Hawkins
