Never mind, I see now that 2.9.1 broke the ability to delete records and 2.9.2 fixed it. Thanks for the quick fix. By the way, two language files show up in Wordfence as changed, so had to uninstall the plugin and reinstall for that to go away.
Referring to the technique at https://www.wordfence.com/docs/using-wordfence-to-analyze-changes-in-wordpress-files/ with the documentation:
I’m seeing a lot of files in a theme or plugin have changed. But when I choose to see the changes, it doesn’t look infected. What should I do?
This problem exists with about 1 in every 20 plugins. It is caused by the plugin or theme developer not following WordPress guidelines on version control. When a developer releases a new version, they must create a “tag” with that version number in the plugin or theme repository. This is a full copy of the version of the plugin or theme they are releasing. Files in this “tag” never change.
Instead what we sometimes see is that the developer is constantly adding new code to their plugin or theme without increasing the version number and without creating a new “tag”. That means that for version 2.4.8 of plugin XYZ you will have an older version than the version 2.4.8 which is in the repository and your WordPress installation will never alert you to upgrade. The only way to upgrade broken plugins like this is to uninstall the plugin, remove it’s files and reinstall it.
Personally we prefer to simply remove plugins that don’t follow the official WordPress guidelines for plugin and theme developers. So if you see a plugin who’s files are constantly changing and the version stays the same, you should consider removing it.
