Unfortunately, the functions file I've posted IS the start. I'd been searching as to why her gravatars weren't posting, and had been trying to find a solution on the internet. I pasted in a bit of code from the gravatar website. It didn't do anything, so I replaced it with the regular code and then poof. The parse error.
So I went to the original functions.php file, copied it and pasted it into the wordpress editor.
now the entire site is down and I've got nowhere to turn and no ideas what else to try.
