Turn off safe_mode in php.ini and restart apache if this is a dedicated or vps server.

If this ISN'T a dedicated server, you can try to do the following if you host allows a local override of php:

1. Create and edit a file named php.ini on your ftp in your public_html/root folder.
2. Add a line with the following and save it to the server in ftp.
php_flag safe_mode off
