I've found a problem. In some browsers like firefox and google chrome for mac there is no topics pagination. After checking the html code I saw that in these browsers the div class="wpf-navi wpf-navi-topic-top" doesn't exist. In safari works it. Also on ipad no topics pagination. But on my iphone it works.
I made two screenshots were you can see the difference.

I don't know how it is on windows.
