On August 18,2009 Craigs list changed their addressing scheme and the change caused an issue with the CraigsList Digester's replicating Advertisment urls.

What happens with CLD versions prior to the 8/18/09 build is that a double slash occurs in the address because of the change.:

<a target=_blank href="http://lasvegas.craigslist.org//cpg/1322335909.html">

Notice the double slashes after the ".org"

We fixed this in the latest buld that you can download here : CraigsList Digester.
