problem after upgradin to 3.0.5

[cybernet2u]

after using ispconfig_update.sh

and leave all the options by default and after all the services restarted i've noticed that whatever vhost i'm trying to access it only display the default welcome page on each one ...

how can i fix this, and ( or ) debug it

the only accessible things are the ISPconfig panel and */phpmyadmin
....

The sites vhost configuration does not get altered on update, so maybe a Listen staement is missing now e.g. if the ispconfig.conf or ispconfig.vhost files on your server had been altered manually. Do you use * or the IP address in your website vhosts?
