The pligg customization is done so onto wordpress for joinmyblue.com…

Making comments show in a popup window will require the following code addition to header.php…

< ?php comments_popup_script(); ?>

It should be placed above the wp_head line. Read more here.

I’ve inserted the code to the wordpess default template and got the following error…

Fatal error: Call to undefined function comment_popup_script()

This was no surprise to me after reading the Understanding comments-popup.php blog article that noted that the Kubrick wordpress default theme didn’t include a comments_popup_script() function that is required to make it happen. So then came the function search.

I found the function at hiveminds.in. Simply copy the code listed on the page and save it as template-functions-comment.php using any text editor. Then upload template-functions-comment.php to the wp-includes folder.

After adding the function, I found that there was still error. There is a way to control the size of the popup window here by use of the wp-comments-popup.php file. It turns out that the wp-comments-popup.php file is also missing from he default theme. Find the source here, then add it to your wordpress install.

Lastly, visit your homepage to see your comments show in a popup window.
