I've installed your plugin on two sites using differents WP themes and different plugins - your plugin being the only one in common between these accounts.
Both websites did reject my WP password and I had to request a new one.
Is this problem related to your plugin? If so - what's the reason and how can it be solved?
I've met the problem twice on the first account (at each new login) and once on the second (though I've logined just once).
