    Hello, I was using the discogs api perfectly in my website discolado.com.br until the last week, but suddenly I received an error (bellow). We already tried everything to solve, but hadn't success. The Discogs support ask if we have a User-Agent defined. I don't know because I'm not a developer, could somebody help please? Bellow the errors I'd pasted the codes. Maybe we were blocked by discogs? Thank you!

    The search function---------------------------------

    'header' => 'Accept-Encoding: gzip\r\n'
    $context = stream_context_create($options);
    $return = file_get_contents('http://www.discogs.com/search?type=releases&f=xml&api_key='.$params->get('discogs_api_key').'&q=' . $query, false, $context);

    JFile::write($write_filename, $return);

    $gzip = new JArchiveGzip();

    $gzip->extract($write_filename, $write_filename);
    $xml = simplexml_load_file($write_filename);

    $search = JRequest::getVar('search');

    $js_function = "get_discogs_release_tracklist" ;
    $button_title = JText::_('Get tracklist') ;
    $js_function = "get_release" ;
    $button_title = JText::_('Get release data') ;

    foreach($xml->children() as $child){
    foreach($child->children() as $child2){

    echo "<div class="discogs_release">" ;

    Yeah, it looks like your client was blocked because it doesn't supply a User-Agent. User-Agents help us identify clients that are behaving badly, and also give us a way to get in contact with the developer.

    Normally you'd do this with PHP's cURL bindings, but since you're using file_get_contents() I think you can do something like this instead.

    ini_set('user_agent', 'DiscoladoBot/1.0 +http://discolado.com.br')

    Either make sure that line is run at least once before any call to file_get_contents() runs, or add the appropriate directive to your php.ini.
