Is there any way I can preconfigure the default settings for a site? For example, I'd like to make sure every new website that is being created has the statistics set to None.
For all settings that are not on the first tab of the site settings, edit the default value of the matching database column in web_domain table with phpmyadmin. The default is then taken when you add new websites, this change is update safe (unless we decide to alter a default with an update, but this rarely happens.
Ah that's awesome, I can work with that. And now that you mention those first-tab settings, where are those?
The defaults for the first tab are defined in the form files in ISPConfig. There is no update-safe way to override them at the moment.
