I just setup a server i.e. Apache 16.04 + Nginx + ISPConfig3.1 based on 15.10 setup tutorial. I faced a problem with my phpMyAdmin (http://server1.example.tld:8080/phpMyAdmin) where upon log in I am being redirected to ISPConfig panel (http://server1.example.tld:8080/index.php). But when I return back to it via back button, I found that I am successfully logged in to it. All website are working fine. I am just posting out of curiousity of what could be the problem and how to solve it as I am thinking to uninstall and reinstall ISPConfig. Any opinion(s)?
