Redmine

Hey, I need help urgent!

We upgrade our debian server and consequently redmine from 1.4.4 to 2.5.2.
Our actual problem is that out API post service is not working. We get a 404 not found page error.

Here you are the parameters and how we are doing the integration:

Server configuration

Debian: 8.0 (Jessie)
Redmine: 3.0~20140825-5 (2.5.2-devel)
Apache : 2.4.10-10 
PHP5: 5.6.7+dfsg-1 
Ruby: 1:2.1.5
Bundler: 1.7.4-1
Rails: 2:4.1.8-1

Integration Service

<?php

require_once ('ActiveResource.php');

class Issue extends ActiveResource {
    var $site = 'http://USER:PASS@redmine.OURSERVER.com.br/';
    var $request_format = 'xml'; // REQUIRED!
}

$issue = new Issue (array ('subject' => 'XML REST API', 'project_id' => '4'));

$retorno = $issue->save();
print_r($retorno);
?>

*Return:*

*[response_code] => 404 [response_headers] => HTTP/1.1 404 Not Found*
