new to dedicated/Plesk

[invi2003]

hello all.

I'm new to plesk to be easy on me.

I created the client(myself)
Created Domain (my domain)
loaded my blog (wordpress) to the htppdocs folder.

now my problem is when I go to preview my site, it takes me to the site ip but instead of displaying the wordpress intallation is forcing me to download the index.php file.

Is there something i missed?

thanks
