XMLRPC Response Error. Probably very easy for some of you!

[eluser]veledrom[/eluser]
Hi,

I have an issue here and am desperate to solve it. Please give me a hand. Please have a look at the response comes from server. I cannot identify which one is wrong, either request or response, maybe both!!!

Error is : The XML data received was either invalid or not in the correct form for XML-RPC. Turn on debugging to examine the XML data further.

Note: I also attached the files, if you wish to run on your local. Just a little and basic one anyway.

Thanks in advance

in your request try

Code:

array(
    array(
        'request' => array('login','string'),
        'username' => array('newuser','string'),
        'password' => array(sha1('123123'),'string')
    ),'struct'
);
