Not sure if anyone can help me with this here but I thought I'd give it a shot. I've been using the IB autogroup app to surf the forum for a couple years without issues. Just last week or so I've suddenly been unable to open threads. Nothing has changed on my phone as far as I know, no big updates or anything.

What happens is say if I open Series 1 tech&performance, no problem, open Series 1 tech garage, no problem, then when I try to open a particular thread I get the Error message "The remote server sent an unknown response. This could be a result of the forum software plugin being outdated or having a conflict". Any ideas?

Oddly I can open all the individual threads in the RX-8 parts for sale/WTB section just fine, but nowhere else can I open threads on the site...
