AddType in htaccess causes page to download

Use AddHandler also, change htm to .htm and add .html

AddHandler application/x-httpd-php .htm .html
AddType application/x-httpd-php .htm .html

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
