Deprecated: Function get_currentuserinfo is deprecated since version 4.5.0! Use wp_get_current_user() instead. in /var/www/html/wp-includes/functions.php on line 5383
It’s indeed a bug, my apologies. To fix it, please download from my repository this file I’ve prepared, unzip it, and upload the contained file via ftp into the following folder: /wp-content/themes/Kabuki/, replacing the existing file.
Thanks for reporting, I will include the fix into the next theme update as well!
