I downloaded again, but I had only just downloaded the extension anyway. Your documentation says the file is dated April 2008, but the previously installed version on the site was March 2008. Same dates applied when I installed the newly downloaded version.
The site is now live and you can see exactly what it's saying at
www.joomlaarticles.com
I also note that the word Advertisement below the banner is hyperlinked but goes to a blank page??
There are 2 banners set up for the one client to get the rotation going, but the second one doesn't show at all.
Cheers,
Ric
