october cms could not find driver

First off I just want to preface that I am on shared hosting on justhost.com so I am not excluding them as a possible culprit and minimal proper PDO support. I just know that the site worked for a while before the error, and very little changed.

I am using October CMS.

I was logged into my backend from one computer, then logged in with the same account on a another computer and i got this error

could not find driver

(sitename).com/vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php line 47

public function createConnection($dsn, array $config, array $options) {

$username = array_get($config, 'username');

$password = array_get($config, 'password');

return new PDO($dsn, $username, $password, $options); }

I have not changed anything except what exists in the themes folder of the site.

I have checked my database config file, and all of that information has remained the same. Is there a direction I should look to solve this?
