Support » Plugin: Ozpital WPWeTransfer » Transfer failed

  • Hi there,

    Quick question; I’ve installed the plugin, but I get the “transfer failed” error.

    Do you know why this might be?

    Thanks on advance!

    All the best,
    – Maarten

    Thanks for the link @maartentak .

    You’re getting a 400 error from the first AJAX request to /wp-admin/admin-ajax.php.

    I get the feeling the plugins ajax actions aren’t being registered in time.

    I need more info. Do you get any PHP errors in your error logs when trying to transfer files with the plugin? They might reveal the issue.

    I’ve checked but my error log doesn’t show any PHP errors on the page.



    Ive just solved this error i think.

    After looking at the curl request sent to the wetransfer auth end point i noticed that it was sending a “content-length: -1” header which was being refused by the server and returing a 400 error.

    in /app/services/OWPWT_CurlService.php i just changed the following:
    `public static function auth() {

    $url = ‘authorize’;

    $response = self::fetch(‘POST’, $url);

    echo $response;

    public static function auth() {

    $url = ‘authorize’;

    $response = self::fetch(‘POST’, $url, array(‘content-length: 0’));

    echo $response;

    Thanks for posting this @stephenskelly , hopefully it helps some others. It’s highly unlikely I’ll be patching the release as WeTrasnfer are working on a drop-in widget which – if viable – could be a drop in replacement for the javascript side of the plugin and do away with the PHP curl requests.

    As you’ll be aware, I’ve removed the plugin from WordPress – I am in talks with WeTransfer and a new plugin featuring the above ‘official widget’ should be online soon.

    It will simplify my codebase and allow me to focus on integration with plugins like Gravity Forms, Contact Form 7 etc.

    If you’re interested I have updated my original plugin to support Contact Form 7 properly. You can find the source code here: – it just never made it to the WordPress plugin directory.
