Warning Undefined variable $unreadPostsCounter / Undefined array key "fid"

After Changing php-version from 7.4.30 to 8.2. I get this warnings:

I had changed line 484 with npp to
"ipaddress" => $db->escape_binary($session->packedip),
see issue #33
(see the file in the zip)

In functions_indicators.php I have some changes for mybb 1.8.38, but the warnings comes with the original plugin file too.
