Php warning after enabling login script Warning: Undefined variable $user_login

Hello

I’m using your feature to hide the login url. When I turn the feature on and place my custom url, and go to it, I’m getting php warning errors. I am still able to login to the website no issues, but the 3 warnings are present on the login page and prefilled on the username entry too. I don’t have an issue with other hide login plugins. I also noticed the page is slow load after the change.

The error: Warning: Undefined variable $user_login in
Version 2.98 | By CleanTalk Security
Php version: 8.1.12

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