OK fixed! The problem was actually the bbPress Notify (No-Spam) plugin. The default body they set to send emails wasn’t using my desired url to the post.
If anybody would like to know, replacing [reply-url] with [reply-replyurl] in the body email (dashboard forum settings) makes the emails attaching a link with the entire topic on it.
(this topic can be marked as solved, my mistake not realizing another administrator installed extra plugins)
I just checked that someone has installed bbPress Notify (No-Spam) plugin. This could be actually the cause of the problem. I will test it and let you know if I find what is going on.
Thank you very much for your help 🙂
