Alias directory for all domains not parse php

[APS_web]

Hi,

i have a server with Plesk 11.5 and CentOs6, i needs to create a virtual directory for all domains, for this i have created a file in /etc/httpd/conf.d/phpMyAdmin.conf, and in this file i have put this:

Alias /phpMyAdmin "/var/www/vhosts/firstDomain.tld/PhpMyAdmin"
<Directory /var/www/vhosts/firstDomain.tld/PhpMyAdmin>
    Options All
    Order allow,deny
    Allow from all
    AddType aplication/x-httpd-php .php
</Directory>

and all it is ok, but files php not be parsed and browser ask me for download of these.
