phpmyadmin php files not recognized

I have installed a debian7-apache perfect server:

Code:

http://www.howtoforge.com/perfect-server-debian-wheezy-apache2-bind-dovecot-ispconfig-3-p4

When i try to access phpmyadmin, browser ask me to save inidex.php.

I have changed into suPHp like here

Code:

vi /etc/apache2/mods-available/suphp.conf

... and comment out the <FilesMatch "\.ph(p3?|tml)$"> section and add the line AddType application/x-httpd-suphp .php .php3 .php4 .php5 .phtml - otherwise all PHP files will be run by SuPHP

so, that cannot be the issue.
I have added

Code:

                php_admin_value engine on

into /etc/phpmyadmin/apache.conf to get

Code:

<Directory /usr/share/phpmyadmin>
        Options FollowSymLinks
        DirectoryIndex index.php

        <IfModule mod_php5.c>
                AddType application/x-httpd-php .php
                php_admin_value engine on
                php_flag magic_quotes_gpc Off
                php_flag track_vars On
                php_flag register_globals Off
                php_admin_flag allow_url_fopen Off
                php_value include_path .
                php_admin_value upload_tmp_dir /var/lib/phpmyadmin/tmp
                php_admin_value open_basedir /usr/share/phpmyadmin/:/etc/phpmyadmin/:/var/lib/phpmyadmin/
        </IfModule>

</Directory>

what do I miss?
