VB this past week I been without at home, today BT has fixed but now everytime I try to go into my user PC, here in the forum I have a message telling

"Your submission could not be processed because a security token was missing or mismatched

If this occurred unexpectedly, please inform the administrator and describe the action you performed before you received this error"

So... is what I doing.

My action before this is just click in the User PC link in the toolbar in the forum, the grey one

Any advice

thanks

Da da-da da-da dah...

Beware the men-of-war!

Your clock is out? That is perhaps feasible.

The canary. WTF is that? It's a computer term relating to an old miner's thing. Put a canary in a birdcage and go mining, if the canary dies get the hell out fast as there's probably lots of gas and you're next.

In computing the same idea is used to validate security sessions. A canary is a piece of information that is put into each web page you visit. When you visit the next page you send back the canary and if it's still valid we give you another canary and we all go about our business safe in the knowledge that nothing is amiss.

What you are seeing is that when you get to the UserCp page, your canary isn't there... or it's old and has expired. It's the equivalent of that canary in the mine dying, and it's an indication to the server that something is amiss and to get the hell out of there... so you get your error message.

The questions that arise:
1) Are you the only person affected? Is it just that a specific link or page is missing a canary value and that affects everyone (this is my problem) or is this just something that affects you and no-one else here sees (this is your environment, so your problem).

2) Does it happen even when you just click on a link? http://www.londonfgss.com/usercp.php If so, then it's likely to be the latter of the above (your environment) and likely to relate to cookies... which yes the system clock can affect.

Basically... step through precisely what you're doing... in real detail as I cannot see your screen. And then if others can let me know whether they are also affected... we'll have it diagnosed in no time.

will do, but this aftermoon, here in my work everything looks to br fine, so, most probably will be my environment.

I will check the battery

If you use Firefox go to Tools->Clear private data and delete all your cookies & authenticated sessions (most likely you won't need to delete anything else).

Beware, this logs you out of all websites (amazon, gmail, ebay...). You will have to re-enter your passwords. Not too much trouble though.

VB, is canary == cookie?

Canary = token passed from page to page.

Implementation is mixed between form fields on the page, sessionId in the Url and cookies.
