You put everything in the wrong place plus your image code was broken

The template has pre defined containers for the post heading the main body of the post and the footer of the post,
Open the file in the building tool then click on 'row' then 'post panel'
then you have the heading body and footer containers thats where the content goes
I put the heading in the post heading container fixed the image code and added the main text to the post body
you need to set the page title and description meta tags from the page options

As for the other it says what it means if you don't get your own comment code you can't moderate the comments
open the /includes/comments panel and the code for the comment box is in the 'panel body' the one you need to get your own version from htmlcommentbox is in the second code block I took the warning text out
