Dear Galaxy development team, I've got a problem using the login function of Galaxy. So I downloaded a copy of Galaxy distribution and installed it on a local machine, then I installed PostgreSQL on this machine and made the necessary changes to the universe_wsgi.ini file and Galaxy is able to the use the PostgreSQL database to store information. I was able to register a user account and then I could login to the system for the first time, but after I logout and login again, the system always says that I am logged out. I checked the log file of Postgresql and the log file of Galaxy system, there is no error message indicating what happened at all. I restarted Postgresql database and Galaxy system and then I was able to login, but after I logged out, I can not login again! Have you guys met this kind of problem before? Any suggestions on what could be the cause of this problem? Thanks so much! Luobin
