Forum layout doubt

[tfmachad]

I don't know what I accidentally changed here. Instead of the usual (at least for me) page with all the posts under a topic, now I get the original post that started the topic and a list of posts under that topic, so I have to click each single post to read them, it's quite unconfortable, so I wanted to switch back to the old style, but I haven't found it yet.

Can someone help me? Thanks in advance.
