In the new config files pdodriver is not necessarily set, this gives an error when saving. See http://codeigniter.com/forums/viewthread/213348/P60/#992337
I've added a check for isset(static::$db->pdodriver) which fixes this issue for me.
Thanks - keep up the good work!
Fixed error where pdodriver not defined in db config
@mecharius Gas ORM repo is always syncing with EllisLab repo (since this repo use EllisLab repo as git submodule), and those line you've pointed is because the new database.php in CI version 3.0 looks like this.
Yeah, I'm using 3.0 for a project so have the config file linked above. Thanks!
