I'm following the instructions on
http://www.dokuwiki.org/install , but when I get to step 4 to open install.php my browser just downloads the file instead of opening it.
If I right click it and say "open with browser" then it is just downloaded again. How do I get out of this? I have the problem both with Firefox and Chrome. This is on Ubuntu 10.10.
Some search results suggested to use "Clear auto-opening settings" in Chrome, however that's already greyed out (so I don't have any).
Anyone have any ideas? Or can I install DokuWiki via command line?
