Hi, First of all, I apologize for interrupting into this discussion, but I have exactly the same problem and did not find a solution yet. And no: prefix and cookies are set properly in our particular setting (as "/")! This is not the cause... I think that the problem occurred with the May Galaxy update, but it was unnoticed for a while. Problem is that the histories of all users are not listed when being asked for it within Galaxy. Only the current history is present for every user. In addition, when I login using another computer, a different history is being depicted (which suggest a cookie issue but I just cannot find it). Copying the current history works but the copy is not listed either. In the postgres database, the histories are properly listed. If I type in the proper history name in Galaxy, I even get the stored history back! So this all works, but users cannot see their histories. The java console does not reveal any problem. prefix and cookie are set properly (I think). So I don't know. Does anyone have any clue on how to tackle this issue? I am happy to provide more information if needed! Thanks!
