I have upgraded my server to 14.04 from 12.04. Deleted all files in etc/apache2/sites-enabled except 000-ispconfig.vhost ,000-ispconfig.conf and 000-apps.vhost. Reinstalled ispconfig. reconfigure all services. But apache fails to start. The error I am getting is Code: * Restarting web server apache2 ...fail! * The apache2 configtest failed. Output of config test was: apache2: Syntax error on line 210 of /etc/apache2/apache2.conf: Could not open configuration file /etc/apache2/httpd.conf: No such file or directory Action 'configtest' failed. The Apache error log may have more information. What step I should take to get the apache start. Thanks.
