[nextcloud11] Operation not permitted in der Log-Datei

Hallo,

In meiner Log-Datei habe ich einige Einträge mit "Operation not permitted"
Passt hier eine Zugriffsberechtigung nicht?
Oder woran liegt das?

Error PHP chmod(): Operation not permitted at /volume1/web/nextcloud/lib/private/Log/File.php#119
Error PHP file_get_contents(/proc/meminfo): failed to open stream: Operation not permitted at /volume1/web/nextcloud/apps/serverinfo/lib/SystemStatistics.php#71
Error PHP file_get_contents(): open_basedir restriction in effect. File(/proc/meminfo) is not within the allowed path(s): (/tmp:/var/services/tmp:/var/services/web:/var/services/homes:/dev/urandom:/volume1/web/nextcloud) at /volume1/web/nextcloud/apps/serverinfo/lib/SystemStatistics.php#71
