Blank page after update on OpenSuSE Linux
The probem on opensuse is caused by a bug in ispconfig 3.0.4.6 and prior versions which had a wrong path in the fcgi starter script for the ispconfig vhost. ISPConfig 3.0.5 did not overwrite the fcgi starter script with a correct path (but writes the correct one in new installations) while switching of mod_php for the vhost on port 8080 to enhance security, the interface does not show up after update. The solution for this issue is described here: http://www.howtoforge.com/forums/showthread.php?t=59609
