Important Installation Failed after upgrade to Joomla ver 1.5.22

Hi,

I recently upgraded by Joomla ver to 1.5.22, due to the requirement of Mootools. The upgrade was successfull and I also set the System - Mootools upgrade plugin to enabled. But when I try to install Kunena, on my local computer, with the following config:

PHP Built on•: Windows NT 6.1 build 7600 ((null)) i586

User Agent•: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13

It gives the following error:

Create kunena_whoisonline ... OK
... FAILED Uncaught Exception: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' '127.0.0.1')' at line 3 SQL=INSERT INTO `jos_kunena_messages` (`id`, `parent`, `thread`, `catid`, `userid`, `name`, `subject`, `time`, `ip`) VALUES (1, 0, 1, 2, '62', 'Kunena', '•Welcome to Kunena!•', , '127.0.0.1');

Can someone please tell me what is going wrong?? Is there something wrong with my MySQL version?? Where is the problem???
