Moodle in british: coffee with milk theme – problems on moodle 2.7

Ubuntu 12.04 server LTS
Coffee With Milk Theme Version 1..2

(2014060400)

error: Class ‘coresessionmanager’

not present in /var/www/moodle/theme/coffee shop_disadvantage_leche/lib.php online 275

Initially I figured that the theme

upgrade might have fixed things, however the same factor was happening after upgrading

towards the latest theme above, and purging all caches a couple of occasions.

I am unsure exactly what the implications of

this warning are.
