@circuscode can you send me the username (profile url or webfinger)?

There seem to be a critical error with the data of your followers: https://www.unmus.de/wp-json/activitypub/1.0/actors/0/followers?page=1&context=full

Can you check the log and/or temporary enable WP_DEBUG to debug the issue?

I have enabled WP_DEBUG.
Opening the endpoint above created the following entry.

Calling the endpoint without parameter does not create an error.

Profile ID is blog@www.unmus.de.

Additional remark: Query Monitor does not show any php error opening the follower overview in the backend.

@circuscode Checking in to see if 7.3.0 has brought back your actors list?

[circuscode]

@obenland Version 7.3 has not solved the issue described above.

But with the help of @pfefferle we have found out the root cause. The crons of the plugin were not active. So the follower data were not updated to the new "format", which made them invisible in the list view.

Thanks, I'll go ahead and close this then.
