### Steps to reproduce 1. Log in as user 2. Click Settings -> System ### E…xpected behaviour The System Monitor shows. Alternatively an error message indicates, that `opcache_get_status()` is disabled and therefore the System Monitor is not usable. ### Actual behaviour I get an internal server error. The following entries are found in the log: ``` [index] Error: Exception: Return value of OCA\ServerInfo\PhpStatistics::getOPcacheStatus() must be of the type array, null returned at <<closure>> 0. /home/webpages/lima-city/#########/www/##.####.nextcloud/lib/private/AppFramework/App.php line 152 OC\AppFramework\Http\Dispatcher->dispatch(OCA\Settings\Con ... {}, "index") 1. /home/webpages/lima-city/#########/www/##.####.nextcloud/lib/private/Route/Router.php line 308 OC\AppFramework\App::main("OCA\\Settings\\ ... r", "index", OC\AppFramework\ ... {}, {section: "serve ...

Hello, I have a fresh install on a hosted-Server. When I try to open the System… /serverinfo tab I got a error. At hosted-servers/shared-hosting-servers is opcache_get_status() commonly disabled. LOG: https://help.nextcloud.com/t/solved-error-while-trying-to-open-system-serverinfo-error-beim-versuch-system-serverinfo-aufzurufen/111672 Now I changed the lines 82-88; https://help.nextcloud.com/t/20-0-1-errors-phpstatistics-opcache-get-status-has-been-disabled-for-security-reasons/97231/4 With this solution it works; ``` $status = (function_exists('opcache_get_status')) ? opcache_get_status(false) : false; if ($status === false OR $status === NULL) { // no array, returning back empty array to prevent any errors on JS side. $status = []; } ``` ;)

Here is a solution someone used under Plesk:

Tyvm, that worked for me. Tried to googled it but didn’t found anything.

Completly empty your disabled functions is bad idea for security reason.

apps/serverinfo/lib/OperatingSystems/DefaultOs.php calls this;
$dns = shell_exec(
$gw = shell_exec(
$iface[‘ipv4’] = shell_exec(
$iface[‘ipv6’] = shell_exec(
$iface[‘status’] = shell_exec(
$iface[‘speed’] = (int)shell_exec(
$duplex = shell_exec(
$output = @shell_exec(

You only need to enable shell_exec function and leave other disabled_function disabled.
