We recently suffered a DoS attack which forced us to recreate our site from a fresh latest Drupal installation, install DoS protection and move the site back to its original location. We did not upgrade CiviCRM (currently using 4.6.0).
The site is back on line and working fairly well, but now only "United States" shows in profiles and contact edit forms. The table civicrm_country looks ok, with all countries correctly listed. Any ideas?
