@vig94 It ended up being a plugin. I disabled all of them, or at least I thought I did, and I was still having the issue. But apparently I did leave a couple enabled. So I did it again…disabled a plugin, checked to see if the issue was resolved, if not then I re-enabled it and disabled another. Repeat until culprit was found. For me, it ended up being Gecka Terms Ordering.
Thank you for the additional suggestion. I tried that as well and I still get the 404 error, unfortunately.
