Fleur de Lys – addons not showing properly

Ok, I try again, since the last thread got alittle out of hand. Ok, my problem is that in the addons I’m having some troubles with, but works normally on other themes, does not use the same layout or css that the Fleur De Lys theme.

So, how do I make the RumWall addon beeing displayed as the other pages? Here is the RumWall (wall.php) code and here is the Fleur De Lys page (single.php) code.

I have tried editing the code without luck, but I wonder if it might be possible to just make a new page and <?php include (”); ?> the wall.php?

PS: I hope I got the pastebin to work correctly this time. I won’t bump, but I’m still trying to figure this out myself, so I will post my further problems/errors as I’m stuck. And Niziol (I think), please don’t reply here unless it’s constructive, no harm intended.

Edit: Forgot to say, that Fleur De Lys has header.php, footer.php and index.php in one file; index.php. Would it maybe be smart to split them up into those three, to make it easier with later addons?
