I have Access denied when : Administer > ... > Custom Data > Display and Edit Custom Fields
I notice that "www." is added between htpps:// and my site name : https://bapa-lacellesaintcloud.com/drupal/index.php?q=civicrm/admin/custom/group&reset=1 is moved to : https://www.bapa-lacellesaintcloud.com/drupal/index.php?q=civicrm/admin/custom/group/field&reset=1&action=browse&gid=1
... and I get the right form when I (manually) remove this "www." from the URL
Why (how ?) is this "www." added ?
BTW : I don't have this error on 2 test sites which are not https but only http ; All my sites have been upgraded to 4.7.2, but I am not sure that this problem was not there before.
