cakephp3 errors..... after edit db info

Hey All

So Im trying to get version 3 running.  Aside from not liking the composer BS Im having a issue with initial install and setup.  I get it running at http://cake3.farsightedmedia.com on the initial setup and works fine as soon as I change the DB credentials 

//'port' => 'nonstandard_port_number',

            'username' => 'my_app',

            'password' => 'secret',

            'database' => 'my_app',

            'encoding' => 'utf8',

            'timezone' => 'UTC',

            'cacheMetadata' => true,

To actual working credentials I am presented with these errors and they dont go away even if I rollback the changes

Fatal error: Call to undefined method Cake\Datasource\ConnectionManager::_config() in /home/farsight/public_html/cake3/vendor/cakephp/cakephp/src/Datasource/ConnectionManager.php on line 80

Fatal error: Call to undefined method Cake\View\StringTemplate::get() in /home/farsight/public_html/cake3/vendor/cakephp/cakephp/src/View/StringTemplate.php on line 176

I have many apps I would like to start porting over to version 3 ........   Ny servers are all CPanel Suphp
