Mark Read - Token expired?

[rockinaway]

Each time I click to mark all forums read I get the token expired message:

Your submission could not be processed because a security token was invalid.

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

What could be wrong?

Again I'm having to see these threads.
Can you look at my sticky on vBulletin.com in the 3.8 forums???
