I have installed the GP premium and need to do some customization for work as per our need, few of the requirements are:
1. Having few custom widgets.
2. Customizing few styles (I know this can be done without child theme).
3. Injecting few additional CSS and JS files
I followed your guidelines and used the same child theme (https://docs.generatepress.com/article/using-child-theme/#installing-a-child-theme) to perform these customization, however, after using the child theme I am getting “GP Premium requires GeneratePress to be your active theme.” message. Though it seems the things are working fine and I can see the customization and other things working as expected.
I am not a WordPress expert and before moving forward, I want to make sure I am not doing any wrong step and having a child theme will not create any issue for me
