I'm using Magento CE 1.7.0.2, having recently upgraded from 1.4.2.0. And when editing/creating a customer address in the backend, the country dropdown field is blank - with no possible options to select. Neither does it work on the frontend address dropdown.
Any ideas what's caused this, the only code hint I could find is: "this.defaultCountries = [false,false];" in the JS on the page, whereas on a new Magento install (same version, same default country) it shows: this.defaultCountries = ['GB','GB'];
#{company}
#{street0}
#{street1}
#{street2}
#{street3}
#{city}, #{region}, #{postcode}
#{country_id}
T: #{telephone}
F: #{fax}
VAT: #{vat_id}'); this.regionsUrl = 'https://www.mydomain.co.uk/index.php/myadminpath/json/countryRegion/key/9a4636b0f154d816edefe750b20a9bca/';` – mattpark22 Aug 22 '12 at 08:30
