Форумы / Cotonti / Support / [MORE] not working in custom skin

I'm using <!--more--> to display Read More link

In nemesis it gives me what I want: http://www.cotonti.com/datas/users/nemesis_more_64.png

In my skin it gives no link and it displays the content below the more too. So it is not only the link that is missing.

How to solve?
