Few weeks ago i did a clean kickstart2 RC2 installation. I did not enable any demo material, and I did not configure nor enable the jirafe functionality.
Today, i have overwritten all RC2 files with the new RC3 files. After that, i ran update.php. 8 updates had to be done. In the end, an error popped up:
Failed: Exception: Jirafe token or application ID missing. in jirafe_synchronize() (line 15 of /var/www/vhosts/adhoco.nl/httpdocs/dev/profiles/commerce_kickstart/modules/contrib/jirafe/jirafe.jirafe.inc).
Since RC3 has just been released today, Joshua Miller advised me to inform you about this.
I hope my feedback contributes to your work ;) I'm happy to hear about the results.
