After upgrading to CiviCRM 4.6.5, I cannot access any more to any popup window. This overlay window is somehow slightly greyed. It doesn't react anymore (not event the cancel button) and the only way to remove the window is pressing the escape button.
In drupal administration I have this warning :
Warning : array_shift() expects parameter 1 to be array, string given dans civicrm_permission() (ligne 67 dans /home/website/public_html/sites/all/modules/civicrm/drupal/civicrm.module).
Is it a Drupal issue or a Civi one ?
Thanks for advice and help.
