Modify the file upload limit

Modify the following options in the /opt/bitnami/apps/owncloud/conf/php-fpm/php-settings.conf file to increase the allowed size for uploads:

; Maximum size of POST data that PHP will accept.
php_value[post_max_size]=4000M

; Maximum allowed size for uploaded files.
php_value[upload_max_filesize]=4000M

Restart PHP-FPM and Apache for the changes to take effect.

$ sudo /opt/bitnami/ctlscript.sh restart apache
$ sudo /opt/bitnami/ctlscript.sh restart php-fpm
