Call to Undefined method error

My test page is @ Welcome to RustedRoot.com

I've followed through the directions to install the module, obtain the API key and entered the information as directed.

If I click on the "Connect with facebook" button - it gives a pop up window showing my site instead of a facebook connect window. If I press the "Connect with facebook" button again - it gives

Fatal error: Call to undefined method dbal_mysqli::getEscaped() in /home/macworks/mac-works.com/dev/root/administrator/components/com_comprofiler/library/cb/cb.database.php on line 596

Fatal error: Call to undefined method dbal_mysqli::connected() in /home/macworks/mac-works.com/dev/root/libraries/joomla/session/storage/database.php on line 85

I use Joomla 1.5.14 with PHP v. 5.2.12

Apparently I don't know how to edit posts either

But my questions are

1- why does the pop up show my page instead of a FB connect window?
2 - What's triggering the undefined error.

I use Community builder on the backend for accounts. v1.2
