An Error Has Occurred!
Session verification failed. Please try logging out and back in again, and then try again.
It seems to be happening on every other posting action (delete post, post reply).
You'll notice that some links (such as the logout link) end in a long code like this:
https://bitcointalk.org/index.php?action=logout;sesc=3da541559918a808c2402bba5012f6cAll forms also have something like this, but it's hidden. The purpose of this code is to prevent CSRF attacks.
If you click a link or send a form that contains the wrong code, then you get the "session verification failed" error. This can happen when your code changes, but you're still looking at the old version of the page for some reason. Aggressive caching could cause this. Or maybe your browser is discarding the PHPSESSID cookie very frequently for some reason; your session code changes whenever you're issued a new PHPSESSID.
There was previous reports of this, check
https://bitcointalk.org/index.php?topic=567343.0 and quote from theymos above.
Don't know it problems are linked, but i had problem accessing forum today, downforeveryoneorjustme.com confirmed it also.
cheers
