I am new to WordPress, lets start with that.
I want to build a blog portal in WordPress Multisite but I can´t get it working for the users to change theme and configure the theme they are currently using. I have tried with child theme but I haven´t get it good. The user must be able to change themes between the ones that are network activated and be able to configure the theme via css or front-end plugin.
What I have understand is that child theme is a must for the user to configure a theme and not changing it for other users using the same theme. I have tried Child Theme Configurator but then the users can change each others child themes.
How do I get this right? Please help a man in need.
