Thank you all for your support. It was the Twenty Twenty Three Theme I was trying to make the child for. I will try both of your suggestions @yogabasics and @bernhard-reiter just as a learning exercise for myself. I have since just went in and worked with the block editor and found that I could create what I needed without the styles that normally would have come with the theme. I am loving the Full Site Editor!!

Thank you, Mike, for responding to this problem I am having.
This still didn’t work. I am still getting the 404 error when I am in cPanel and try to go to the dashboard of blueridgeadventuretours. Below is what I have set in my DNS Zone Editor first for heartsgroup.org, then followed by blueridgeadventuretours.com. Please let me know if you see anything that should be changed.

It didn’t work by changing it to point to blueridgeadventuretours.heartsgroup.org, so I will try pointing the CNAME to heartsgroup.org.

I am trying to fix this by going into the Domain Zone Editor in cPanel. I found that blueridgeadventuretours.com CNAME was pointing to itself as you said. So, I just pointed it to blueridgeadventuretours.heartsgroup.org. It can take up to 4 hours to take effect, so I will let you know if it worked. (I wasn’t sure weather to point it just to heartsgroup.org)
Thank you for responding.
