As you can see, the sidebar is getting knocked down alongside from the comments, and above the footer.
I’ve tried adjusting the “contentleft” width but it changes nothing. I’ve also changed the sidebar width without change. So, I don’t think that the width of anything is too large and knocking the sidebar down. The comments_template.php call is in the right place on page.php.
I’m lost I can’t think of anything else to change to get this comments page to render properly like the other pages.
