It seems users may still be experiencing issues. Users who encounter problems should report them in the normal way, either via this thread, or the Contact Us link at the foot of the forum (for users who may still be unable to log in).
However, before reporting issues users should clear their browser cache and all HHO cookies - make sure no HHO pages are open in any tabs before proceeding to clear cache & cookies.
Thank you to those who have provided constructive feedback recently, it was invaluable and very much appreciated.
