WP Admin User Login Issue

Hi there,

Since the newest version of WordPress, our WP Admins (who have adjoining accounts in Simple Membership) are unable to login. I get the screen that says “Warning! Simple Membership plugin cannot process this login request to prevent you from getting logged out of WP Admin accidentally.”

Not sure if something changed, or if I accidentally unchecked a box.

Thanks in advance!
