Where is my post?

I have tried to make a new post twice now but it’s still not showing in the forum. I did get a message saying my post had been created, but there was also a ‘401 you are not allowed to view this page’ message at the same time.

I was giving this forum another chance, after being very irritated by the technical difficulties previously, but it looks like the problems are still here. I really dont want to be typing long messages (with difficulty due to hand problems that I am sure many of us share) that then vanish. I think I will have to get my advice elsewhere.
