The plugin for wordpress is developed by Adam Hupp and the modified version (v1.2.2) can be downloaded from here.

• Login to Facebook and create an application
• Note the API Key and Secret code
• Download the plugin (http://www.techwhiz.in/repository/zip/fbconnect v1.2.2.zip)
• Login to your blog and install the plugin
• Open ‘Facebook Connect’ Plugin Options and Enter the API Key & Secret code
• Open the file ‘comments.php’ located in your theme folder of your blog
• Insert the following code where you wish to show the facebook connect button

<?php do_action(‘fbc_display_login_button’) ?>

• Save the ‘comments.php’ file

The most common error is that the comments posted on wordpress may not be published to your facebook’s live feed. This generally occurs when you use a link instead of button in comment form to initiate submit action.

The following code for ‘Submit Comment’ link should not be used:

<a title="Submit Comment" href="javascript:document.commentform.submit();">Submit Comment</a>

However the following code to generate ‘Submit Comment’ button is recommended:

<input name="submit" type="submit" id="submit" value="Submit Comment" />
