I'm using a new installed CiviCRM 4.7.8. with Drupal 7.5 ( Database system version 5.7.12-0ubuntu1 - PHP 5.6.22-4+deb.sury.org~xenial+1 )
The installation was done without errors but now I get:
Notice: Undefined index: values in _civicrm_api3_api_resolve_alias() (line 2310 of /var/www/html/sites/all/modules/civicrm/api/v3/utils.php).
Warning: Invalid argument supplied for foreach() in _civicrm_api3_api_resolve_alias() (line 2317 of /var/www/html/sites/all/modules/civicrm/api/v3/utils.php).

on clicking "New Mailing".
Any idea what's wrong or how to solve this error?
Thank you
