I connected the device to the server, changed some options in the chart settings and it stopped working.

Thanks

Hi @adrian.dusinski,

Thanks for reaching out! I’m in touch with the devs who are preparing a fix, and there are two workarounds for now as far as I can see.

1. adding all your devices to a group, as the bug seems to be triggered by the “ungrouped” selection.
2. removing the widgets, you can do this via your browser console

```auto
const { token } = JSON.parse(localStorage.getItem('JWT'));
const url = '/api/management/v1/useradm/settings/me';
const res = await fetch(url, { headers: { Authorization: `Bearer ${token}` } });
const etag = res.headers.get('etag');
const settings = await res.json();
settings.reports = (settings.reports || []).filter(r => r.group !== '*|=ungrouped=|*');
await fetch(url, {
    method: 'POST',
    headers: { Authorization: `Bearer ${token}`, 'Content-Type': 'application/json', ...(etag ? { 'If-Match': etag } : {}) },
    body: JSON.stringify(settings)
  }).then(r => console.log(r.ok ? 'fixed — reload the UI' : `failed: ${r.status}`));

```

This should remove the crashing widget.

I did both option and it helps.
