Uploading SilverStripe version 3 on live server

Silverstripe Version: Version 3

Question: I Created my silverstripe Locally, and now Im trying to upload it to live server. I already change the _config.php for database and change .htaccess rewrite rule to something like this:

    SetEnv HTTP_MOD_REWRITE On
	RewriteEngine On
	RewriteBase '/'

After running the url, I get

Server Error
Sorry, there was a problem with handling your request.

What am I missing? Please Help

Check your server’s php error log; and/or set your environment to ‘dev’ (in either _config.php or config.yml).

You can find more verbose details there.
