I'm trying to get Roundcube installed in my Perfect Server setup but I am getting a 502 error when i navigate to http://ip/webmail (forwards me to http://ip/roundcube). I uninstalled squirrel(y)mail and tried this http://www.howtoforge.com/forums/showthread.php?t=63483&highlight=roundcube and the associated instructions here http://www.howtoforge.com/using-roundcube-webmail-with-ispconfig-3-on-debian-wheezy-apache2 I don't really know what all I should post for information and this feels like I'm just saying, "It's broke. What's wrong?" My normal server environment is Windows so this is a bit of wading into unfamiliar waters. Please let me know what else I should look at to get this up and running. Thanks!
