Version 2.1.0 not working

When I upgraded from version 1.1.3 to 2.0, it no longer worked.
When calling the stored in the 1.1.3 version of the question and answer link, I’m redirected to the login to another website. The Web page that sends unauthorized there. I could not log in anymore.
I then deleted the plugin via FTP. Yesterday I installed the version 2.1.0, enter question and answer and the unauthorized persons sent the website.
However, the new login link is incorrect. The old man was: https://site.de/wp-login?question=answer. But now he is https://site.de/question=answer
The wp-login and wp-admin is no longer Stealth and can still be called. Whereas the Stealth Login steers me to the HOME page

What to do?

I am so embarrassed. I noticed the double wp-login.php and mentioned it to a friend, but we didn’t realize that the stealth was gone.

It obviously worked before because now I have a lockout on my main site today so I’m going to rectify that immediately. Sincere apologies.

2.1.1 is live. Please update immediately.

I have updated to version 2.1.1. It does not work .. My Stealth Login link is still: https://site.de/?question=answer
wp-login and wp-admin can still call.

I can’t replicate that – hit my contact form on my website (Google me) and I’ll get your login to see what is up.

Installed 2.1.2 and everything is working OK, my Stealth Login Link is as it should be.
Thank you.

Thanks for checking back in. Glad I was able to resolve it for you with these latest changes to the coding.

Hello. I just downloaded the plugin to the latest version and NOW it works again ?? However, is there something I noticed. Some China bots have found the link and try to Steatlh registered animals now with the Stealth link. I make this feature off, but I wonder how the bots come to the link. ?? I send you on your Form more information
