Users unable to log in

Hi,

I have been using this plugin for quite some time and it works great. Just some of the users told me they were unable to login from past few days.
One been a user for a while and he been having some problems with that and can’t login. There are some other who tried to login for the first time and they can’t login at all.

Please advice.
