install.php doesn't run

[NickDeGraeve]

I'm trying to install Mantis 1.1.4 on a Ubuntu Server 8.04 but I don't succeed because install.php isn't parsed,

I extracted the tarball to /opt/websites/apache/mantis-1.1.4 and I created a symlink to /opt/websites/apache/mantis. I created a symlink called /var/www/mantis that points to /opt/websites/apache/mantis.

If I try to access Mantis at http://localhost/mantis (or http://localhost/mantis/admin/install.php) I get prompted to save the PHP file. Other PHP files, eg. http://localhost/mantis/admin/index.php, are correctly parsed and displayed.


Any idea what might be wrong?

Thanks.
