Hi Lewis,

Open:
data/config.pl in a text editor.

Find the line that calls the feedsearch...looks like this:
$FEEDSEARCH_SSI_URL = "http://blogbomb.com/cgi-bin/BBx2";;

You need to change the URL to match your own domain and set up.

This should fix the preview problem...But should not affect if the SSI tags work on your pages.
