I am having the exact same problem. Did you find out how to resolve this error?
Any info would be helpful.
Thanks Peter!
We saw this after the last update we did and it didn’t seem related to that. I will try this again in the hopes its a bug that will be corrected by an update. I suspect its some break in communication between plugins and WordPress home servers that trigger the update alert. I was hoping there might be some troubleshooting process to test the plugin connections. I will try to update the core WP software and see if that has an effect. I had read one guy had to manually update all plugins and then they started showing update alerts and working as expected. I will post my result either way.
