As of writing this post, our Wordpress engine has just been upgraded to the latest version of the Wordpress, the version 2.3.1.

What’s the Wordpress 2.3.1?

According to the Wordpress site, Wordpress is our current stable release of the Wordpress which means some bugs found with the Wordpress 2.3 were fixed :

2.3.1 fixes over twenty bugs. Some of the notable fixes are:

• Tagging support for Windows Live Writer
• Fixes for a login bug that affected those with a Blog Address different than
  their WordPress Address
• Faster taxonomy database queries, especially tag intersection queries
• Link importer fixes

Now, I think you need to upgrade your Wordpress 2.3 system too. Consider this:

 Unfortunately, some security issues were found in 2.3. Janek Vind found an XSS problem that can be exploited if your php setup has register_globals enabled. For this reason, upgrading to 2.3.1 is advised.
