I use ispconfig 3 on several servers for years and really love it. It gets better with every release. I am having this issue on 1 server, not sure when it started, but I am no longer able to login. It does not do the normal: Error Username or Password wrong. as it does on my other servers when typing the wrong password. I've upgraded it to the newest release using the upgrade script, but have the same results. You can view the problem here: http://184.108.40.206:8080 Anyone know what I can do to fix this?
