single.php headache

Hello all,

I am having one of those days when I just CANNOT workout what is going wrong. I designed a friends website about 3 years ago and for some reason the single.php is not showing comments correctly directly after posting a comment.

This is the result I get after posting a comment. As you can see it does not show the actual article above the comment. Something is broken and I don’t know what.

This is my single.php code: https://pasteit.com/16821

Can anyone advise what might be going wrong?

Many thanks,
Karl
