try move the span tag in the "Forum Display Templates" -> forumdisplay_thread_multipage
That edits something else. When you see the forum display. any idea how to eidt the thread display?
When using the default theme its something like this; open your forumdisplay_threadlist template
Find
{$multipage}
Change into
<div class="float_right">
{$multipage}
</div>
Will probably be simular for your Theme.
It's going to be in a different template than forumdisplay_threadlist most likely.
