Do not show information

Hello,

I installed the plugin, but it is not showing me anything (https://screenshot.net/pt/2rnopt2).

I activated the plugin also in my subdomain and I see that it shows me an error (https://screenshot.net/pt/9kygmu1).

My site is in multisite network. I tested activating the plugin on the network and also tested activating on the sites separately, but it only shows me these 3 information.

The page I need help with: [log in to see the link]
