The frustrations of plugins

Posting, so that someone else won’t have to work quite as hard to solve this problem.

I created a new website, installed the Wordfence plugin (version 8.1.2), got my license key for the site, installed it, and I keep getting the “Wordfence installation is incomplete” with the banner across the top of the screen. Even after entering the license key repeatedly.

Opening the console did not show any errors.

I cleared my cache, turned off all my other plugins, rebooted both Chrome and computer. Nothing changed.

Finally, I deleted the Wordfence plugin with all of the associated data and tables, and then reinstalled it. And it immediately started working.
