Unable to Add User after Site Migration
After migrating a WordPress 4.7.2 site from staging to production, everything seems to be working fine except that I cannot add a new user. The All Users screen shows my existing 2 admin accounts that came from my staging site, plus a blank line with no name/edit button etc, which looks like a ghost entry. When I click on “Add New” I can enter and submit a new user, but it never shows in the list of users. Any tips to what happened and what I need to do to fix this?
