Help Can't download from internet on samsung galaxy s4

[Mattis]

Hi, as the title says, i can't download any apps from my browser on my s4. The appstore works perfectly fine, but when i try to download an app from a website, it says "starting download" but it never goes any further.
I've obviously enabled "unknown sources" under security in the settings.

Does anyone know what the problem might be?

Best regards

Well you did everything fine and I'm guessing maybe you disable the download manager I did that once or try another browser like chrome see if that works
