When I click on 'mark forums read' I get this error 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.
...however, after doing this, if I log out then log back in then everything is showing as 'read'. Doesn't really bother me but just wondered if anyone else gets this message in case it's something to do with my computer?
