Apologies. I don’t mean to be dense – I just don’t understand it.
Is this correct.
1. I install main theme.
2. I install child theme.
3. I make the child theme activated/live.
4. When it comes to updating I only update the main theme? And then it upgrades the child theme?
5. Is there any degradation in speed/performance on the live site when using the activated child theme?
6. Are all plugins like cache plugins installed on to the child theme or the main theme?
