That would be the only difference but you have that method as well so I'm not sure why you can't but I can without making any changes...so odd. Can you download the example you uploaded to the Forum and retest with the downloaded ZIP? I wonder if uploading it here fixed the MIME Type.

Cheers.

    Downloaded and tested - no change.
    But i have tested it on a mac - there it works.
    But on every W11 PC i tested -> failed.

      The problem ist that $file['type'] and FileObject::mime_type($file['tmp_name']) do not return the same result.

      in case of a zip-file:
      string(28) "application/x-zip-compressed"
      string(24) "application/octet-stream"

      samplefile attached

      tmp.zip

          Yes, I have seen this with someone else, however I’m unable to replicate this with ZIP files in my instance. What version of PHP are you using? What browser are you using? What OS are you using when uploading the file?

          Cheers.

              Ugly Fix:

              class.forms.php replace the function

              static function isValidFile($file) {
    // Make sure mime type is valid
    #var_dump($file['type'], FileObject::mime_type($file['tmp_name']));die;
    #if (!empty($file['type']) && strcasecmp(FileObject::mime_type($file['tmp_name']),
    #            $file['type']) !== 0)
    #    return false;
    // Check invalid image hacks
    if ($file['tmp_name']
            && stripos($file['type'], 'image/') === 0
            && !exif_imagetype($file['tmp_name']))
        return false;
    return true;
}

              KevinTheJedi do you used my ZIP-file?

                  If I were you I’d install a vanilla osTicket and retest there. We do not support the German version. They make customizations to the code so it’s not official osTicket.

                  Cheers.
