Hallo, We have a productive environment and now Apache2 won't start anymore. web74 no longer exists. It has been deleted. Apparently, web74 is still in the system and has not been deleted correctly. The administration is not starting either. Everything is offline. Please help. Urgent! Thank you.
Find the config of the corresponding website in /etc/apache2/site-available and delete the file. Also delete the symlink in /etc/apache2/site-enabled. Apache should be able to start after that.
Most likely reason is that someone duplicated the vhost file manually, or you used certbot manually outside of ISPConfig which duplicated a vhost file. Do: cd /etc/apache2/sites-available/ grep web74 * to find the vhost file. Then go to /etc/apache2/sites-enabled/ folder and delete all symlinks in that folder that points to that website.
Yes, thank you! There was another subdomain for a test page. I found it and was able to delete the vhost.
