The debug_information hook should return an array. Since the handlePluginHealthInfo method in your code does not exist in the WPEWPAdmin class, it is returning NULL instead of an array.

This bug causes the following problems:

1. The WordPress Admin > Site Health > Info page is empty.
2. If a plugin uses the debug_information hook to add data to the Site Health > Info page (i.e. LearnDash), it will throw a Fatal Error.
3. Any plugin which directly calls WP_Debug_Data::debug_data() expecting an array (i.e. Site Reviews) will throw a Fatal Error.

Here is a screenshot of the invalid code in your plugin:

Hi – I began 2 local sites last year via Local by Flywheel. I realized only recently there is a new Local Lightning because my old Local would not even open. So they’ve helped me migrate Site A over (and I think I may have to start Site B from scratch). For some reason in the new Local when I click on Admin from the Local Sites app, it is not accepting my www.remarpro.com log in. Any ideas how to troubleshoot? Thanks!
