PHP doesn't catch POST data - php

Question

I have a dynamic form for upload a image or a YouTube video to slideshow. But when i click send, the server doesn't catch the data. I can see in my browsers network panel that I send a post request to the server that is populated with the parameters. But when the server gets the request the $_POST array is empty.
The code worked before but I haven't been working on for like a half year but it worked just a few weeks ago. Only thing I have been doing is working on another website and change some PHP settings at my webhotel but I can't find any that would stop POST requests.
I removed all the input fields since SO wouldn't let me post so much code.
