I use some Facebook applications with some sites I work on, and lately when you use the multi-inviter to invite people to something on Facebook, when they click the notification, they get the message "this request has expired" and are unable to accept the request. Supposedly it's quite a few people having the issue, as seen on the Facebook Developers platform http://bugs.developers.facebook.net/show_bug.cgi?id=17113 . Wondering if anyone here has/had the issue and has solutions?
Thanks.
