Verifying that your smartCARS web scripts are properly installed and configured is important to the operation of the smartCARS client. This article explains how to do this and the possible issues you, as an airline administrator, may have to deal with.
Add "frame.php" to the end of your "Script Location" URL and visit it in your browser.
The output of the URL you visited should be "Script OK" followed by version information. (This information may vary depending on what web interface you are using.)
If you receive the message "Failed to connect to the database.", this means that the web script cannot connect to the database. Verify that it is installed in the correct location and has access to the appropriate configuration files.
If you receive a message stating that "class PDO is undefined", you need to contact your host and ask them to enable PDO (PHP Database Objects). If you are your own host, enable the library within PHP.
