Has anyone seen this error before?

I am getting this response when trying to access some threads on Pprune. Nothing in my set up has changed since earlier when it was working fine.

Is this my problem or a Pprune problem?

Thanks!

There was some sort of maintenance outage yesterday evening on the site and I needed to reset my cookies this am - I suspect it was part of that.

Edit: Went to specsavers. Mind you, I do believe in resting my cookies too.................

Yep I had to sign in here this morning as well, it's not this end as all 3 browsers were doing it, I also got a weird message about revalidating encrypted data when using the back button to get back to the forums list.

Thank you all. Indeed I was forced to log in again this morning and the problem seems to be solved. Back to the beach!
