title: PHP file upload on server changed mime-type to application/octet-stream
body: <p>I have a file upload and when I test it on localhost all mime-types are ok.
  (txt, pdf, doc, docx, xls, xlsx)</p>
  
  <p>When I test the same files on the server it changes all mime-types to application/octet-stream.</p>
  
  <p>Is there any setting in PHP.ini or anywhere else to set it?</p>
  
  <p>Server is using WAMP.</p>
  
  <p>PHP Framework Nette</p>
