Dear, I have a problem after upgrade to ISPConfig 18.104.22.168p1 (from 22.214.171.124). After followed the instruction in here: http://www.howtoforge.com/forums/showthread.php?t=65688 . Everything look okey, but there are some mistake when i did some testing: When I change some email password in ispconfig panel, it is not change in end user email, still the same password. I think something went wrong in DB synchronize, isn't it ? Any helps, thanks very much. P.S: My system has 5 servers: 1 ispconfig master (just ispconfig master), 1 web server + DB, 1 email, 2 DNS servers. What I did was I just updated on ISPConfig master.
