If you are running multiple websites with Apache2 with mixed ports (usually http port 80, https port 443) change following configuration files. Variable NameVirtualHost should be only in file virtual.conf, find and comment it in other configuration files!
FOB: I recently reported being stuck trying to set up multiple SSL name-based virtual hosts on the same IP address with non-SSL name-based virtual hosts. Soon after, I figured it out. Shortly after that, one of my students suggested the same solution to me.
/etc/apache2/conf.d/virtual.conf
#
# We're running multiple virtual hosts.
#
NameVirtualHost *:80
NameVirtualHost *:443/etc/apache2/sites-enabled
<VirtualHost *:80>
ServerAdmin webmaster@zviretnik.eu
ServerName zviretnik.eu
ServerAlias www.zvietnik.eu
...
<VirtualHost *:443>
ServerAdmin webmaster@zviretnik.eu
ServerName www.zviretnik.eu
ServerAlias zviretnik.eu
...The ports 80 and 443 should be also defined in following configuration file.
/etc/apache2/ports.conf
Listen 80
<IfModule mod_ssl.c>
Listen 443
</IfModule>
<IfModule mod_gnutls.c>
Listen 443
</IfModule>Also check your /etc/hosts file, if DNS name and IP address is correct.

FreeNX is a system that allows you to access your desktop from another machine over the Internet. You can use this to login graphically to your desktop from a remote location. One example of its use would be to have a FreeNX server set up on your home computer, and graphically logging in to the home computer from your work computer, using a FreeNX client.
It’s Open Source, secure (SSH based), fast and versatile! License: GPL
FreeNX server:
sudo add-apt-repository ppa:freenx-team
sudo apt-get install python-software-properties
sudo sed -i 's/natty/lucid/g' /etc/apt/sources.list.d/freenx-team-ppa-natty.list
sudo apt-get update
sudo apt-get install freenx
wget https://bugs.launchpad.net/freenx-server/+bug/576359/+attachment/1378450/+files/nxsetup.tar.gz

If Apache server status page http://zviretnik.eu/server-status error 403 page not found appear, the solution could be modification of .htaccess file of WordPress. Mode rewrite has to have following rule:
# Stop Processing if you see server-info or server-status
RewriteRule ^(server-info|server-status) - [L]
# The Rewrite Condition below did not work
# RewriteCond %{REQUEST_URI} !=/server-statusDon’t forget, that server status is accessible mostly only from localhost. If you want to change it, you have to edit /etc/apache2/mods-enabled/status.conf (Allow from localhost).
In case you upgrade to Apache2, it may happen that your Gallery 3 show following error message when you try to change permission on album or photo:
Oh no! Your server needs a configuration change in order for you to hide photos! Ask your server administrator to enable mod_rewrite and set AllowOverride? FileInfo? Options to fix this.
If you have mode rewrite enabled (a2enmod rewrite) and your virtual host directory configuration already contain “AllowOverride FileInfo Options“, than problem could be in your /etc/hosts file. The localhost entry has to have also FQDN name of your server, for example:
