I have a very strange problem. When a search is performed and if it comes up with more than 2 pages, when on the second page the sidebar disappears. Page 1, 3 and 4, etc. Will still show the sidebar.
My website is http://www.peterahrens.com.au, the site isn't finished yet and only has filler content for articles but if you search the term "in the 30" it will come up with 4 pages.
Hope this makes sense?
