XML Parser error

I am running Squid 2.6Stable13 on FreeBSD 4.9 as a transparent proxy
using wccp. I get the following error when I do a search on the search
engine www.aardvark.co.za:

Warning: Sablotron error on line 1: XML parser error 3: no element found
in
/var/www/html/hyperseek_2003/cgi-bin/search/data/custom/google_adverts.inc
on line 74

Warning: Sablotron error on line 1: XML parser error 3: no element found
in
/var/www/html/hyperseek_2003/cgi-bin/search/data/custom/search_plugin.inc
on line 101

Any idea where I should look to solve it?
