If you are trying to use SQLite on a HostingController based server we may need to enable SQlite and PDO in php in order for this to work.
The best way to find out if this is the case is to create a small file named: phpinfo.php containing
<?php echo phpinfo(); ?>
to your site and then running that page.
If SQLite is enabled there will be two sections, one labeled SQLite and another labeled PDO.
If this is not the case please contact our helpdesk via our customer portal and ask that it be enabled.
