According to the latest report that James Joul wrote two years ago, the listening now reports have stopped working again. I noticed this weird bug on every artist page I'm visiting. I don't believe the extensions are causing this issue. I visited the artist page by using incognito mode and I'm still not able to view recent listeners, or a complete calculation for the last several weeks, months or annually. View any artist page if you don't trust me. Account: Samson-91. It has been like this since yesterday.
We had to temporarily disable the people listening now widget on artist pages, as it was causing the realtime charts on https://www.last.fm/dashboard, https://www.last.fm/charts, and https://www.last.fm/ to fail. It'll be restored once we understand and address the underline cause. Sorry for the inconvenience caused in the meantime. :(
