I just setup a virtual host on the same server that I am hosting another site (totally different domain names same IP). Anyways, the main page of my new site shows ads that are definatly for the other site. All other pages on the new site show correct ads for the content. Is this going to correct itself (the site is only a couple days old)?
I'm having exactly the same issue now. Another account on the same host with the shared IP address is showing the other accounts ads on the home page but the right ads on the other pages. Did this correct itself for you?
