Hi, I've upgraded my local copy of SilverStripe from 2.2.3 (I deleted the 2.2.3 versions of cms, jsparty & sapphire and replaced the folders with the 2.3 versions) and everything *appears* to have worked. The site still works, admin's fine, too. But when I try to flush the db, it starts building the db and creating db records, but then stops and I get an error:

Website Error

There has been an error

The website server has not been able to respond to your request.

Also, SilverStripe now seems slow, which is odd as it's only installed locally.

Can anyone help, please.

Many thanks in advance.

Set your environment to "dev" and see if you get a more useful error.

Ie, in _config.php, add:

Director::set_environment_type("dev");
