I am not using multiple Solr cores, but I hadn't restarted after making changes
to the solrconfig file or adding a data-config file, so I did that and got a
"severe errors" warning in my browser, with the below text in my logs. When I
delete the data-config file and remove the DataImportHandler section from the
solrconfig file, I restart and see Solr running fine (although, of course,
without the data import handler), and when I go in and repeat the process, I
get the same errors.
I suspect that the fact that the data-config file is blank is causing these
issues, but per the documentation on the website, there is no indication of
what, if anything, should go there - is there an alternate resource that anyone
knows of which I could use?

That usually means that DataImportHandler is not registered at /dataimport
in solrconfig.xml. Another reason might be that you are using multiple solr
cores? Did you restart solr after changing the solrconfig.xml ?
