Hey,
go to the Admin-CP and go to change templates. Open the Template you want to edit and search for the template header. Open it and you find
<img src="$theme[logo]" alt="$settings[bbname]" border="0" />
in it. Add align="center" so that it looks like this:
<img src="$theme[logo]" alt="$settings[bbname]" border="0" align="center" />

Then try this:
[color=red]<div align="center">[/color]<a href="$settings[bburl]" class="logo"><img src="$theme[logo]" alt="$settings[bbname]" border="0" /></a>[color=red]</div>[/color]
For me it works fine.
Greets,
Michael
