[Solved] Embedded Graphs not showing up

Help
1

Since the update last night, not all graphs are showing up.

In the log we see following error message repeating.

Running daily.sh again didn’t help.

as an initial workaround i added

use LibreNMS\Config;

to /opt/librenms/LibreNMS/Cache/PermissionsCache.php

namespace LibreNMS\Cache;

use App\Models\Bill;
use App\Models\Device;
use App\Models\Port;
use App\Models\User;
use Auth;
use DB;
**use LibreNMS\Config;**

class PermissionsCache
