<h5><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h5>
Most of the errors showing are from this - I feel like there is some kind of nesting issue here but I don't know how to find it. I got that code from the wordpress codex so I'm assuming it's not actually that bit of code that's the problem. Any thoughts?
There's also a an extra </div> at the bottom of index.php that makes no sense. I have it there because when I take it away the entire site goes haywire.
