WPS limit login caused crash with lastest wordpress update

on our wordpress site your plugin had been working wonderfully for years.
but with lastest wp update. the backend of the site became unavailable. ipage tech support found your plugin to be the cause and deactivated it… things went back to normal after that.

Just wanted to let you know.

Thanks for all you guys do.
