Answer 1

I got the same issue here for some reason I can't upload pdf files a quick troublshooting was to display errors

$msg = $this->upload->display_errors('
', '
');
echo $msg;

I got the error message of invalid file type , so I added anew line of code to display full information about the file to uploaded.

$msg = $this->upload->display_errors('
', '
');
$msg.=print_r($this->upload->data());
echo $msg;

then I copy the file type to config/mime.php

'pdf'   =>  array('application/pdf'),

and make sure that the same mime type is used as the mime type of my uploaded file. The funny part was that the error was that in mime.php there was a typo :)

apostrophe instead of single quote as a result of copy past from internet without paying attention to quotation marks used.
