This plug-in provides a simple chat system integrated into your blog.
I've run into this problem with people using themes that don't properly call wp_footer(); in their footer.php Please ensure you have this line in footer.php in your wp-content/themes/whatever/footer.php file:
<?php wp_footer(); ?>
<?php wp_head(); ?> in it's wp-content/themes/whatever/header.php` file.

AjaxChat searches for your wp-config.php by looking three directories up. So, if you put AjaxChat in /var/www/wp/wp-content/plugins/ajaxchat, it will look in /var/www/wp for wp-config.php. If it's not finding it try to put ajaxchat under wp-content/plugins/ or change any references to wp-config.php by hand.
