I'm using this plugin on multiple site.
As I tried logging into one of my site, I got blocked out because my IP changed and I need to confirm my email.
I did receive that first email, and manage to log into the Dashboard and worked on my site.
Then I tried logging into another site, and since my IP changed I couldn't log in and received needed to confirm email login.
However, I never gotten that email.
Then I tried again with another site, same thing...and didn't get an email from that 3rd site as well.
I'm not sure what's going on here? Is this plugin only sending one email per changed IP address, meaning we can only use this plugin on one site then?
