I installed it and see it and set up some of the options but nothing is showing up on the posts to allow someone to make a comment. What am doing wrong?
Maybe you could post a link to your site so we can take a look? Also, check if your public_html folder has an error_log file - if so, have a look in there for the recent errors.
That is, I assume you read all the installation instructions, and the plugin(s) and component are properly enabled, and you have all the prerequisites. Also is this JoComment3 or 4?
