I made a new layout for my site and I uploaded it, but when I fixed the permissions for my index.php file with my FTP client, it didn't seem to have any effect (same server 500 error or whatnot). So I used the fix file permissions tool, and now it displays this:
Parse error: parse error, unexpected T_STRING in /home/robynie/public_html/index.php on line 1
I don't know what that means!

I tried reuploading and fixing the permissions both ways again, to the same result.
Please help!
