when I try to add external links in mailouts i get the following link: https://MYDOMAIN.COM/modules/civicrm/extern/url.php?u=300&qid=8370
when I click on it, there is an error: Could not load the settings file at: /usr/share/drupal7/modules/civicrm/../..//default/civicrm.settings.php
Civicrm is part of Drupal 7 in my installation. my php version is PHP 5.4.45-0+deb7u1 (cli) (built: Sep 10 2015 08:34:47) the install runs on debian wheezy
please help..
edit: the problem seems to be in this function: function civicrm_conf_init() {
in the civicrm.config.php which is located here: /usr/share/drupal7/modules/civicrm/civicrm.config.php
