PHP Warning – Undefined array key “path”

I’m receiving an undefined array key “path” error for login-lockdown.

Path is /public_html/wp-content/plugins/login-lockdown/libs/functions.php line 106

$is_rest = strpos($current_url[‘path’], $rest_url[‘path’], 0) === 0;

Anyone got any ideas on what changes I might need to make to this line of code to fix the error? I’m not technical so please baby steps.

Thank you!
