Opcache is not properly configured

sudo nano /etc/php/7.0/fpm/php.ini

Uncheck the following:

zend_extension=/usr/lib/php/20151012/opcache.so
opcache.enable=1
opcache.enable_cli=1
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.memory_consumption=128
opcache.save_comments=1
opcache.revalidate_freq=1

sudo systemctl restart nginx

Or   sudo nano /etc/php/7.0/mods-available/opcache.ini 

Add...

zend_extension=/usr/lib/php/20151012/opcache.so
opcache.enable=1
opcache.enable_cli=1
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.memory_consumption=128
opcache.save_comments=1

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

sudo nano /etc/php/7.0/fpm/pool.d/www.conf

Uncomment

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

sudo service php7.0-fpm restart

Same Origin error

fgrep -Ri "x-frame-options" /etc

Block out (Add #)

add_header X-Frame-Options "SAMEORIGIN always";

to look like

#add_header X-Frame-Options "SAMEORIGIN always";

 Add this line for local Storage. Then add app.

sudo nano /usr/share/nginx/nextcloud/config/config.php

'files_external_allow_create_new_local' => 'true',

No memory cache has been configured

First add memcache on my tips page then.

sudo nano /usr/share/nginx/nextcloud/config/config.php

'memcache.distributed' => '\OC\Memcache\Redis',

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

'memcache.locking' => '\OC\Memcache\Redis',

'redis' => array(

     'host' => 'localhost',

     'port' => 6379,

     ),

sudo reboot
