Hi martinbeasnunez,
The “Comment Form Selector” is ‘#commentform’ in your example which is the default value; so you can set the option to an empty string. This selector needs to match the <form> tag.
The “Comments Container Selector” needs to match a container element that contains the comment list; probably some parent element of <div id=”respond”>. Have you tried the plugin’s default value?
Unfortunately your example code does not contain the html code of the comment list, so I do not know if such a container exists in your theme. Which theme do you use? Is the theme or your page public available?
Hope this helps,
Jan
