Thank you all for answering. Must be something happening my end! I did see some posts written today but the majority were well out of date. The thing that struck me was the absence of political input about recent happenings. Whereas Gransnet is totally different and Mumsnet is also usually discussing the latest happenings. This morning I could only see old posts.
Do you log off then log in each time?
If not, perhaps try doing that.
You haven't accidentally flipped the threads, have you, to show posts in reverse order? I think Flip and Customise are at the top of the thread.
