@sohan7 Thank you for the reply. Yes, I know what is a child theme. Now. I did not know 1 week ago.
Yes, the site loads fine. This is the issue: when I switch to TwentyTwentyFour theme it looks completely different. But actually my current theme is TwentyTwentyFour, onlu customized.
The question is again: Can I revert to TwentyTwentyFour theme and move all modifications, customizations to a child theme?
