Accessing the site by the above IP address gets the CentOS Welcome page … which is normal when there is no index.html page to serve out. So that tells us Apache is indeed running and responding.
But, it appears to be a DNS configuration and/or in conjunction with virtual apache configuration problem. 'virtual apache' in this case means single IP address serving out different domains.
Accessing http://qurq.net gets Internal server error.
Without more information concerning these other 'domains', it's impossible to assist you. So what is the domain associated with the files that appear to be in the 'site1' directory? 'site2' directory? And do each of those sites use a different DB and data directory?
