Thank you, Lauren.

After dismissing the notice and deleting the plugin, I no longer see the notice pop up. I am going to declare victory and move on. Thanks again for your patience.

Thank you for your patience with me.
I renamed the directory wp-content/plugins/early_this-day-in-history.

The plugin is no longer active. There is now a link to delete it from the plugin list. Before I do, however, I am still seeing the MathRank notice: Rank Math has detected a new post type: tdih_event. You may want to check the settings of the Titles & Meta page and the Sitemap. Will that disappear when I delete the plugin?

And if it matters at all: I never made any entry into This Day in History. I also never created a widget for it.

But deactivating is the problem. I can certainly SFTP and remove that plugin directory, but will that impact the tdih_event post type notice? I see that if I could deactivate and remove the plugin it would take care of tdih_event post type, but not by deleting the directory, or does it?

Are there any database entries created that need to be removed? What about the new post type: tdih_event that RankMath discovered?
