file upload not working due to file type

[eluser]bhbutter123[/eluser]
I am using file upload class and it is telling me I am trying to upload a file of a type not allowed. Here is what info I have:

$_FILE['userfile']['type'] = application/vnd.openxmlformats-officedocument.spreadsheetml.sheet


In Controller
$config['allowed_types'] = 'pdf|doc|docx|xls|xlsx';

Try adding your extension in config->mimes.php in codeigniter if the file type you are trying to upload is not present in the mimes.php.
