[Plugin: Peter's Login Redirect] Cannot access admin after installing plugin on multisite insta

I’m also having this problem. Using WordPress 3.1 and Peter’s Login Redirect 2.0.0.

When I try login, the login box doesn’t shake to indicate a bad username / password, it just does nothing. If I reset the password, I can get in but as soon as I logout, I can’t login again without resetting. When I disable the plugin, everything works perfectly.

Please help!

I’ve noticed that if I go to https://www.domain.com/wp-admin it sends me to https://www.domain.com/wp-login.php?redirect_to=http%3A%2F%2Fdomain.com%2Fwp-admin%2F&reauth=1 and then I can’t login.

If I manually type in https://www.domain.com/wp-login.php I can login again. It seems that it just has a problem with the standard login url that WordPress takes you to when you go to /wp-admin.

Note: I’m running the single site version, not the multisite install.
