Free extensions for Joomla!

Is there anybody who can help with Joomla 1.0.15 + Xmap 1.0.4 and estaeagent_plugin?

I got always this warning:

Warning: Invalid argument supplied for foreach() in /home/skip/samuivillas/administrator/components/com_xmap/plugins/estateagent.plugin.php on line 51

Warning: Invalid argument supplied for foreach() in /home/skip/samuivillas/administrator/components/com_xmap/plugins/estateagent.plugin.php on line 70

and no links of estateagent in Sitemap.

http://samui-villas.biz/index.php?option=com_xmap&sitemap=1
here the life site sitemap generated by Xmap.

Any help or suggestion, please.

Yeah, you can start searching in websites.
