Ahh, I seem to remember this issue... yep -
http://www.vbulletin.com/forum/proje...?issueid=28367 It's a bug. I think you can get around it (until they fix it), by opening the template spacer_open and finding this line:
HTML Code:
<div class="page" style="width:$stylevar[outerdivwidth]; text-align:$stylevar[left]">
And replacing $stylevar[outerdivwidth] manually with the width your want.
