I have on my ubuntu server 2 web servers. First is apache2 and second is lamp. On lamp running my webside (port 80) and on apache i have virtualdomain on port 8081 8082 8083. I install isp on apache2 and isp worked. But when i reboot server isp do not run. I found that when i have on configure file (/etc/apache2/ports.conf) listen 80, isp is running but virtualdomain no. When i delete listen 80, restart apache2, isp not working but virtualdomain yes. what shell I do? How start up isp and virtualdomains? Thx.
