I am using the notices feature to direct users to two auctions to raise money for the family of a recently deceased member. In the notice I am using direct links to the threads in our for sale forum. When some users click the links they are reporting that they get logged out ( I think it still takes them to the link). This has happened before on xf1.2 but I was not a user here at the time and couldn't ask for help. Any ideas what is causing this and how I can fix it?
