What is a $_FILE[user][error]=> 6 I can't find Error level 6 in the manual or on Google. Here is my files array: [userfile] => Array

        (
            [name] => Readme.txt
            [type] =>
            [tmp_name] =>
            [error] => 6
            [size] => 0
        )

Doesn't make sense. Readme.txt is simply a small text file on my local HD. Note, type doesn't register either. Weird.....
