Nextcloud version (eg, 12.0.2): 13.0.5
Operating system and version (eg, Ubuntu 17.04):
Apache or nginx version (eg, Apache 2.4.25):
PHP version (eg, 7.1): 7.0
The issue you are facing:
After upgrading from 13.0.4 to 13.0.5 using the web updater I only get a white page after the last step and then returning to my nextcloud home.
I tried “occ upgrade” but only get this:
(uiserver):~/owncloud$ php7.1-cli occ upgrade
The process control (PCNTL) extensions are required in case you want to interrupt long running commands - see http://php.net/manual/en/book.pcntl.php
