Thanks for pointing me in the right direction. That last part gave me a redirect loop error, so I changed it to this:

rewrite ^/(.*)$ /index.php?url=$1;

I applied it, loaded the site, restarted nginx, and loaded the site again. It seems to work. Hopefully, my change is not just a fluke but will continue to work. However, if you think my change will cause an issue for the future, please let me know. Again, thanks for your help.
