Administration panel > Template

I've been trying to follow the tutorial on Recent Topics (https://help.forumotion.com/t90639-latest-topics-new-system) But I've encountered a small hitch. It says that after editing the Recent Topics Widget, I should go to Administration panel > Display > Template > General > Overall_header. The only problem with that is, on both the simple and advanced version, I can't seem to see any 'Template' section. Is it under a different name? How can I access the section?

Hi, templates can only be accessed if:

=> You are the forum founder.
=> Your forum is running on either phpBB 2 or PunBB.

That would explain it, I'm not the forum founder, just a friend of the founder. I'll tell him he needs to do it. Thanks for your help ^^
