404 in all routes

My base_url:
$config['base_url'] = _Env::BASE_URL;

My ENV BASE_URL:
'http://new-domain/wr'

My structure:
wp-admin/
wp-content/
wp-incudes/
wr/

the wr (the CI part) folder contains:
ci/
->application/
->system/

Please note that it's the same structure as the last server except for the different domain.

Thanks a lot!
