Redirect Loop

Thanks for this great plugin!

It has been working great for months, but just today it started throwing a redirect loop. Deactivating all other plugins has no effect. I’ve also deleted and reinstalled the plugin, but still the problem.

I’m the only admin, and I did nothing to the backend for the past week. I’m stumped! I’d be grateful for any help.
