I just purchased a parent and child theme and see both sitting in "available themes" in WP. Earlier, I "activated" the child theme (only - as I thought you only active the child and not the parent theme) and I got a fatal error, and locked out of WP. I uninstalled and reinstalled WP from my c-panel.
Here I am again, with both parent and child themes in "available themes." Do I have to activate both themes? If so, does that mean changes are being made to the parent theme?
