Problem with accessing my website, it downloads the index.php file

[Max12]

Hello,

Like described in the title, when clicking on whatever link to my site, it downloads the index.php file.

I don't understand where this error can come from, I never had this for six months since I started my website.

Can somebody help me with this?

Thanks in advance! 

Max
