[Plugin: Maintenance Mode] Blank page, can’t login to site as admin today!

Hi, I had a major issue today. Sometimes when I’m maintenance mode I have to re-login now and then as I get bumped off for some reason. Today, though, I now couldn’t login at all. I got a blank page where I usually access mysite.com/login/, which I defined in settings.

I’ve tried removing the maintenance mode plugin directory and clearing my browser cache but no change. Sometimes I would get this: https://www.site.net/login/?redirect_to=http%3A%2F%2Fmygsite.net%2Fwp-admin%2F when trying to type wp-admin. I replaced wp-admin with wp-login and I was able to get the login page to come up.

Does anyone know why this happened and how to avoid in the future please? Thanks.
