When I go to https://archaeologicalbodies.org/, I get a “this domain is available” page.

Thank you!

Well I did and had to buy the woman on an auction. Changed the name servers to that of my own host and thought the site would re-appear. But no! No response at all and I cannot even log in. My host support says there is a php error!
What can I do? The site can be reinstated by the host to the original Dazzling child’s theme but it will loose all changes.
Does anybody have any suggestions?

Thank you!

Looks like you have a problem in your theme. FTP into your site (or use whatever file management application your host provides) & delete the /wp-content/themes/dazzling folder to automatically activate the default theme.

I will try this!

But- then I will loose all custom changes……

can you share your function.php file using pastebin
