It’s possible I broke something in the new bb_safe_redirect however I have tested it working and I have not seen any other complaints (and there have been several registrations on my site).

Actually I just noticed you said it doesn’t work with 0.9.0.5 which didn’t have my change.

Have you tried deactivating your plugins temporarily to see if any interfere?

Let’s look at what changed from 0.9.0.4 to 0.9.0.5
