Permalink not active

Hello,

Someone else had fidgeted with our template, and the ability for a post to go to its own page is non existent. Does anyone know what code is needed and where to insert it in order to re-activate this?

Not sure what file is needed to look at – css, index, or what, so let me know and I can paste it here.

Thanks!
