I’m not sure if I was clear. I still show a post number of 1 on the forum page but I did end up using css to get rid of the reply(post) on the Topic page.
.forums .bbp-body bbp-reply-header:nth-of-type(1) {display:none;}
.forums .bbp-body .bbp-reply-position-1 {display:none;}
Again, that was just to hide the first reply(post/comment) to a topic.
The goal on the site was to have pre-set Topics as questions that users could reply to. Did not want subscribers to create new topics.
