Messes up blog even after being removed

This plugin messed up my blog.

Even after I removed it, I would occasionally get the following error:

“You have been logged out.
The password you submitted was wrong.
Security Provided by Platinum Mirror LTD (programmer: Daniel Chatfield)
login / Password
Login”

I asked for support a week ago but to no avail. Plugin author is not responding and my blog is still messed up.

Until my issue has been resolved, I won’t remove this review.

Think twice before using. There are many free, better alternatives out there.
