problems after installation

Hi!

Thanks for this great product!

I have the following problem. After the installation (Joomla 1.6.3) when I try to open, from the components menu, items like maps or placemarks I have error messages like this

Fatal error: Call to undefined method JDatabaseMySQLi::escape() in/var/www/vhosts/radicisenzaterra.org/httpdocs/administrator/components/com_zhgooglemap/models/zhgooglemaps.php on line 116

Can you help me please?
Thank you!

I'm sorry, but I think I can't fix it, because I support for j2.5 and for j3.x

There are many features now used started in 2.5, and I don't downgrade to 1.6
