Pagenation

Yes, unfortunately, there are several themes that mess up the pagination control. I can’t answer you specifically, because I don’t know what your theme is doing, but I do know that if you look at the CSS rules that apply to the element inside each LI element, (it will be an A or SPAN) that element should be floated left. This is what causes the pagination links to line up horizontally.

You may need to ask for help in a support forum for your theme, as this is the source of the problem.
