The old Limit Login Attempts plugin hasn’t been updated or supported for a few years now. It’s was a very popular plugin a couple of years ago and even now quite a few sites are still using it. A team of developers from wpchef.me decided to create their own fork and called it Limit Login Attempts Reloaded. It has everything the old one had but includes support and now all the recent updates and bug fixes. It can be downloaded from Limit Login Attempts Reloaded.
