The updates seams to work just fine as you sayed because as a guest all the profile feeds are viewble and I see several accounts updated today.

What Lock Down ask about your skin Im also curious about but also if this issue occurs when you use the default IP.Board skin?

The other thing is that error mess. Seams connected to some hook with a name of " HideContent HanEmail ". You might wanna consider deactivate any hooks with that name and see what happens if you havent already.
