Getting Raw data on registration submission

Hi,
When a user tries to register and hits submit he is shown the raw data like below, instead of an error page or success.

array (
‘message’ => ‘Invalid user ID.’,
‘dump’ =>
array (
‘ID’ =>
WP_Error::__set_state(array(
‘errors’ =>
array (
‘existing_user_login’ =>
array (
0 => ‘Sorry, that username already exists!’,
),
),
‘error_data’ =>
array (

)),
‘display_name’ => ‘ ‘,
),
‘changes’ =>
array (
