International shipping rates are broken

[Axelerator]

Hello guys,

 

We are using osCommerce v 2.2-MS2 (It is old version, but we made a lot of changes here). Two month ago international shipping (Priority Mail International) stopped working. But we didn't change anything in this area. Domestic shipping is working fine, but international is not.

 

Result:

When international customer is trying to checkout his order he sees:

"Priority Mail International (6 - 10 Days) (Not Available in Your Area) $0.00"

 

I tried to change existing 'Priority Mail Int' to 'PRIORITY MAIL INT' or 'PriorityMailIntl' in this mapping:

                $this->intl_types = array(
                        'Global Express'                                        => 'Global Express Guaranteed',
                        'Global Express Non-Doc Rect'           => 'Global Express Guaranteed Non-Document Rectangular',
                        'Global Express Non-Doc Non-Rect'       => 'Global Express Guaranteed Non-Document Non-Rectangular',
                        'Express Mail Int'                                      => 'Express Mail International (EMS)',
                        'Express Mail Int Flat Rate Env'        => 'Express Mail International (EMS) Flat Rate Envelope',
                        'Priority Mail Int'                                     => 'Priority Mail International',
                        'Priority Mail Int Flat Rate Env'       => 'Priority Mail International Flat Rate Envelope',
                        'Priority Mail Int Flat Rate Box'       => 'Priority Mail International Flat Rate Box',
                        'First-Class Mail Int'                          => 'First-Class Mail International'
                );

 

but it doesn't help.

 

Did anybody face this issue?
