Hi Andrea,
I have also similar problem which is related to memcache. I installed php5-memcache, php5-memcached, memcached. But in moodle, i am not getting green tick mark as memcached plugin which is shown in image
When i try to check php5-memcache, memcached and php5-memcached in command line then i am getting as newest version is available.
Please tell me, how can i enable these memcached ? Am i doing anything wrong ?
