Similar problems for me. I was unable to add a post in the usual way last night – the page just "hung". (I could generally add a post using "Quick reply".) And on first trying to open any page of FT, I would get a message that the "page had been re-set" –.trying again usually brought the page up.

And today I find that I am unable to delete a private message – when I try, the page hangs and eventually times out.

All of this seems to be FT-specific; I am not finding problems with other websites.

ETA: The private message has been deleted, but only after six or so attempts and a long, long wait.
