Error displayed and email sent

I’m getting emails saying the plugin is experiencing a technical issue. The plugin seems to be operating OK. An error appears at the bottom of my View all Plugins page. I have uninstalled and reinstalled the plugin but error still shows.

Error at the bottom of the page:
