UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Post Layout Settings Not Working

UBB 7.7.1

In the control panel:
Display > General > Topic & Post Display Settings > Post Layout
I updated post layout to TOP instead of SIDE.

We run 2 forums.
Changing this setting worked as expected on 1 forum but not on the other.

Any idea what would cause this?

Thanks in advance for the help.

More Info:

We are using a different style on each forum.
The one that worked is using: UBBT 76 - Pine
The one that didn't work is using: UBBT 75 - Crimson

I tried changing the style to Pine (this is the style that is selected on the working forum) and it still didn't work.

I checked permissions and they all checked out "OK".
I also cleared the cache.
I checked the /includes/config.inc.php file and the POST_LAYOUT setting is "top".

Still didn't work.
