AddType in htaccess causes page to download

Question

I have read about 10 questions like this, but there seems to be no answer to this simple question.

What could cause .htm files to be downloading instead of executed

Answer 1

I had the same issue but then i figured the version of php i'm using is php5. I changed the handler to the following and it worked!

AddHandler x-httpd-php5-3 .php
AddHandler application/x-httpd-php5 .php
