No memory cache has been configured.

To fix this error make sure you have latest php5-apcu installed:

sudo apt-get install php5-apcu

edit config.php

sudo vi /nextcloud/config/config.php

add the following line in your directive

'memcache.local' => '\OC\Memcache\APCu',

restart the webserver

sudo service nginx restart

php does not seem to be setup properly to query system environment variables. The test with getenv("PATH") only returns an empty response.

To fix this error edit php5-fpm config file

sudo vi /etc/php5/fpm/pool.d/www.conf

uncomment the following line


env[PATH] = /usr/local/bin:/usr/bin:/bin

and restart php5-fpm

sudo service php5-fpm restart
