I don't succeed to run php pages in some domains

[samuelbp]

Hi
Maybe it's an obvious issue but i don't succeed to see the scripts work in certain domains. I get a download message from the browser instead of a normal page (php) i even tried phpinfo with the same result.
1-I created a new unlimited plan with access to scripts and with anything enabled
2- I removed .htaccess from the directory and from any upper directory

Tks
