Sorry, I'm really desperate now. My server has been online and working correctly for a few years by now. Today my main domain started pointing to an incorrect directory, more specifically to /var/www. This means that when anyone tries to access my store the server shows the list of domains and webXXX directories from the server instead of any sites. Apache is running, since the sites show up is I browse to the domain link. I'm now looking for a solution, but if anyone could help it will be more than appreciated!
