After working with HostGator tech support, ended up rolling back from WP 5.5 to 5.4.2 and now everything works. There were a few other widgets on my WP 5.5 install that were not operating correctly but now are fine again with 5.4.2. Guess I’ll wait until they get more of the bugs out of WP 5.5 before upgrading.
Consider this closed for me.
