Hey Delbert and thanks for reaching out!
Sorry for the trouble here. I checked to see if the same issue was happening in a default WordPress Twenty Fifteen setup and everything worked well, so I think you’re hunch about a theme or plugin conflict is spot on.
I know searching for conflicts can be tedious, but we’ve put together a guide to help make it easier. Are you able to run through the steps outlined here and let me know what you find? It’s totally fine to use a test site instead of your current one if you want to avoid interrupting any traffic to the site.
Let’s start there and see what we find.
Thanks!
Geoff
