FineUploader says "No files were uploaded"

Question

I am in the first stages of using/trying fineuploader, so I tried to build an example following the tutorial and I am unable to get it to work. It is always just retrying and in the log returning "No files were uploaded" that means $_SERVER['CONTENT_TYPE'] was not set.

I used the html like the one on the page in the section "Putting it together" (also downloaded the needed css, js and linked it to my php code): http://docs.fineuploader.com/quickstart/02-setting_options.html My php server code is exactly the one from https://github.com/Widen/fine-uploader-server/tree/master/php/traditional.

Can somebody please help me?

EDIT: I am actually trying in on two different servers now, there are 2 different errors in the browser console : For built-in php server:

"[Fine Uploader 4.3.1] Retrying java.jpg..." jquery.fineuploader-4.3.1.min.js:16
18:37:30.195 "[Fine Uploader 4.3.1] Sending upload request for 0" jquery.fineuploader-4.3.1.min.js:16
18:37:30.199 "[Fine Uploader 4.3.1] xhr - server response received for 0" jquery.fineuploader-4.3.1.min.js:16
18:37:30.199 "[Fine Uploader 4.3.1] responseText = {"error":"No files were uploaded.","uploadName":null}" jquery.fineuploader-4.3.1.min.js:16
18:37:30.199 "[Fine Uploader 4.3.1] Received response status 200 with body: {"error":"No files were uploaded.","uploadName":null}" jquery.fineuploader-4.3.1.min.js:16
18:37:30.200 "[Fine Uploader 4.3.1] Waiting 5 seconds before retrying java.jpg..."

For apache httpd:

"[Fine Uploader 4.3.1] Retrying java.jpg..." jquery.fineuploader-4.3.1.min.js:16
18:36:55.356 "[Fine Uploader 4.3.1] Sending upload request for 0" jquery.fineuploader-4.3.1.min.js:16
18:36:55.361 "[Fine Uploader 4.3.1] xhr - server response received for 0" jquery.fineuploader-4.3.1.min.js:16
18:36:55.361 "[Fine Uploader 4.3.1] responseText = {"error":"Could not save uploaded file.The upload was cancelled, or server error encountered","uploadName":"java.jpg"}" jquery.fineuploader-4.3.1.min.js:16
18:36:55.361 "[Fine Uploader 4.3.1] Received response status 200 with body: {"error":"Could not save uploaded file.The upload was cancelled, or server error encountered","uploadName":"java.jpg"}"

The request method is the same, no matter on what server I am running:

My opinion is that the problem is with the servers.

My code:

The problem “No files were uploaded” occurred only for the php built-in web-server and after switching to httpd has never occurred again.

The writing problem with the httpd server was caused by the SELinux.
