My homepage is gone but header is still there

jjj reported that the issue has been solved in the comments to the original question:

…In the mean time I did some trouble shooting with the plugins page
and it turns out the ‘sitemap’ plugin may be the culprit. It works
fine after I deactivated that plugin. I will definitely debug however.
Thank you again
