phpmyadmin requesting to download a php file...

[Luca Ferrari]

Hi,
I've followed the instructions on the ubuntu forums and mailing list to 
install a lamp based on mysql and phpmyadmin, but I'm not getting the latter 
working. I've installed apache2, libapache2-mod-php5, php5, phpmyadmin, 
mysql-server.
I'm able to point my web browser to a test.php page that simply prints the php 
environment, and it works. After I installed the phpmyadmin package I see a 
link in the documentroot, that is the phpmyadmin/ directory. But when I try 
to point my browser to http://ip_address/phpmyadmin the browser asks me to 
download a application/x-httpd-php file.

I've run the a2enmod php5 command, and my apache2.conf file has the following 
lines related to php:

root at ftp:/etc/apache2# grep php /etc/apache2/apache2.conf
Include /etc/phpmyadmin/apache.conf
DirectoryIndex index.html index.cgi index.pl index.php index.xhtml
#AddType application/x-httpd-php .php
#AddType application/x-httpd-php-source .phps
AddHandler application/x-httpd-php .php


Now I don't know what to do to get phpmyadmin working. Any idea?

Thanks,
Luca
