Other plugins were not the problem, but I upgraded to a newer version of WordPress and now it is working fine.
OK, I found the Screen Options section, but there is no Head and Footer Code check box there. there are 12 boxes from “format” to “Revisions” but nothing for header and footer.
When I scroll down to the bottom I do not see header and footer options. I see only word count and custom fields.
I have searched through settings and I cannot find a setting to turn it on. Under settings is a “Header and Footer Code” section but it only contains site wide header and footer.
