We have a Wordpress site, [lifering.org](http://lifering.org), hosted on GoDaddy. We recently upgraded our virtual server's Linux operating system, which involved rebuilding the site from a backup. 

Now I our single posts are displaying TWO comment reply forms. I'm sure we only had one comment reply form per post before. 

I don't know how this happened - I took the backup myself - or how to fix it.
