I have set up Wordpress with a multisite network. I have been searching around for hours and can't seem to find much documentation on setting custom defaults for all the new sites that are created on the network.
I am using a theme with a child theme installed.
Firstly I would like the default theme for all new sites created on the network to be my child-theme that is installed and Every new site starts with a basic default static front page.
Could this work or should i add it as a function in mu-plugin:
/** Sets default theme for new sites on network */ define( 'WP_DEFAULT_THEME', 'theme-child');
Secondly, Every new site created I need to give access to all administrators on the network. Allowing them to work on all the sites automatically.
Should I try and create a mu-plugin if so please give some direction, or if there is a different way please advise. I haven't coded much in php. Please advise how this can be done.
