All my posting history has disappeared

[Lostallhistory]

I use an iPhone, Safari. Just clicked on on my Mumsnet page only to find that all my posting history has disappeared. It asked me to create a new user name , I tried to use the last one I created but it said it wasn't available.
I've been here years and it's as if I've never used the site before.
@MNHQ what's going on?

Just checked a thread that I posted on and I can see one of my posts but when I click on Threads I'm On , it doesn't show any.

How strange, just clicked back on the page and everything has come back and reverted back to my original name .

Were you definitely logged in? Sorry I know that's a bit obvious but it sounds like you were logged out for some reason!

Yes definitely logged in
