I've been searching around and I know that this is a common issue, but some posts on my page are causing the sidebar to be pushed to the bottom. http://theaugur.org/page/2
I learned that it's good to use http://validator.w3.org/check?uri=http://theaugur.org/page/2 to check for errors on your page, but those seem to be errors in the html. How do I figure out what to change in the actual css or php in order to fix the html?
If those errors aren't the issue, what else can I try to do to fix this problem?
