Open_basedir restriction in effect

Really great software, just what i needed, so thanks for that. I am only struggling with the following error.

The motion chart shows up but above the following message appears:

warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/) is not within the allowed path(s): (/home/w5438328/:/tmp:/usr/local/lib/php/) in /home/w5438328/domains/gavoor.nl/public_html/cipb/includes/file.inc on line 444.
