I'm running ispconfig on a debian server with 10 slave ispconfig servers to host websites, databases and mail. On the master server I created a custom vhost template for nginx. Is it possible to apply the modified vhost template to existing websites? The reason I'm asking this is because there are a lot of websites hosted on the servers which would take a lot of time to recreate manually.
You have to modify the template on the slave, not the master. Then run tools > Resync to apply the change to alls sites.
