I have installed some comments extensions (disqus and Jcomments) and both of them are set just after the article content by default. It does not allow me to change it to any other place. I would like to move it to the bottom part, but I don’t see where to change it. Is it possible at all?
you can change the template to default Joomla template it will be same,
Or you can ask the extension team it can be published on a module position.
After content means just after the article content and its not a module position.
