I'm trying to set up the Webpost script for the first time. Following the steps in the readme.txt file I opened the config.php file and put in my database information. Then when I go to run the admin/install.php script I get the following error:

Fatal error: session_start(): Failed to initialize storage module. in /usr/www/users/siriusq/sirius/ts/admin/db_inc.php on line 475

Any hints?

Thank you in advance
