Comments/Amplify Theme

I successfully followed the directions given to provide a “Leave Comment” link at the top of each blog post. (I can’t seem to link to the support page where we discussed this.) However, something happened and the site crashed. I did a backup and followed your directions again, and now whenever I add the code the site crashes. Is there an easier way? I am a recent convert from Blogger to WP and I am comfortable with editing HTML code, but dealing with php files is scary. All I want is my little “Leave a Comment” link back. It can’t be that hard!! I am dying over here!
