I bought a premium theme for my managed WordPress blog which includes a child theme. I installed both but activated the parent theme and started working on it (just adding logo and stuff) since I wasn't aware of the difference it makes but didn't modify any code. Is it too late to switch to the child theme? Can I still activate the child theme and continue to receive updates for the parent? Are there any downsides of using a child theme? If I have to switch to the child theme, do I need to uninstall and re-install both the parent and the child and start over?
PS: The theme is called Zephyr by UpSolutions. It includes a third party page builder plugin called Visual Composer. The theme options also have a header builder add-on which I used to customize the header on the parent theme. Purchased on Envato Market.
