Didn’t work for me either. I did the update via FTP following the instructions in the Documentation file and had to try uploading a couple of times. Finally, after a successful transfer, when I went to my site I saw this:
Parse error: syntax error, unexpected $end in /home/content/57/12156657/html/wp-content/themes/cvcard/functions.php on line 1049
I went back, deleted it and re-uploaded my back up theme folder and the site reloaded fine.
