I have a user that is using Safari 3.1.1 and they keep getting a security token error when they use the back button. Does anyone what is causing this and how to fix it? I am not a Mac user and would like to keep my Mac users happy.
He also may need to empty his browser cache.
If only one user is having the problem then it's probably a client side issue. Some browsers will resubmit the form if you backtrack onto a page that had posted data, like a reply page. That is a possible explanation.
I haven't seen this problem reported before. Make sure he is running the latest version of Safari (version 3).
Thanks guys. The client got back to me and told me that it started working all of a sudden and he did not do anything. So for now I am good it looks like.
