I'm getting an error message when I try to use the Quick Links > Mark
Forums Read link. It says "Your submission could not be processed because a security token was invalid."
I used to be able to do use it until a couple of weeks ago (very approx!), but the last few times I've tried I've got this error instead.
I've tried it on Firefox and Konqueror on Linux, and Firefox on WinXP. Both through a proxy, but different proxies.
Donna suggested I post here and see if anyone's got any idea what's going on.
