I was trying to solve a problem with 40 second timeout 500 errors today, and in the process, I mucked up some setting, and now neither ISPConfig3 nor phpmyadmin will load. Apache2, fcgid php, mysql and ftp are all working for client sites. I can't find anything in the error or system logs, and I can't find any problems with the files I was tweaking (apache2.conf, fcgid.conf, my.cnf). I even compared them with the files on a VM server that's working OK. A reboot didn't fix the problem. System Details: VM Ubuntu Server 9.10, "Perfect Server" setup, ISPConfig 18.104.22.168, fast cgi, suexec.
