But every plan  they have includes this:
# phpwiki Supported
# phpmyadmin Included

could it be that their php is outdated?
i can't contact them about it, because i'm being hosted by the guy that's paying the bills, along with other persons, so i myself don't have hosting with them.

let's start by saying that i'm not very techy, and that i did run a forumsearch for this.

I've copied the punBB 1.2.6 files to my server, and then when i want to open install.php, it opens the source. how can i make it open the page?
I do realise how stupid this sounds, mind you.
i don't know the specs of the server i'm hosted on, and the website doesn't seem to show them either: http://webqualityhost.net/
