 $config['create_thumb'] = TRUE;

}

Answer 1

Check your curly braces here:

if(!$this->upload->do_upload()) echo $this->upload->display_errors(); else {

it looks like you're mixing syntax styles. Blank screens are usually caused by a "catastrophic" syntax error.

Answer 2

$config['source_image'] = 'uploads/' . $fileName;

try remove $fileName,become

$config['source_image'] = 'uploads/'
