I recently started getting errors in the control panel on a site that has not been touched in a while.

Message: is_dir(): open_basedir restriction in effect. File(/home/hosting/webs/headsup/heads-up.com/web/themes/) is not within the allowed path(s): (/var/www/clients/client23/web44/web:/var/www/clients/client23/web44/private:/var/www/clients/client23/web44/tmp:/var/www/heads-up.com/web:/srv/www/heads-up.com/web:/usr/share/php5:/usr/share/php:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin:/usr/share/php)

Filename: libraries/Core.php

Any idea what could have caused the issue?
