User control panel not working either

So I thought it was goaccess that quit working.  But also the the graph of bandwidth consumption has also stopped working since March 31.  March 30 was the last time any data was saved.  So this might be a cron issue after cwp update.  I can run go access from shell but daily records are not happening.  I can see all data prior to march 31 in both goaccess and bandwidth consumption.  Houston we have a problem.

No one has anything to say about user bandwidth consumption disappearing?

I haven't encountered the issue and probably don't fully understand what you are seeing. Have you tried manually running the root and user cronjobs from the shell so you can watch their output and ensure they have run (to validate your hypothesis)?
