Just update my test forum from beta 8 to beta 9 and found these errors in the System Logs.  These columns never existed in the core_statistics table of my database, should they have?

Same thing happened on four of my test upgrades so it's not a one-time occurrence.

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.

 

This issue has been resolved in 4.7.0 which has recently been released. Please upgrade to that version to resolve this, and of course, let us know if you are still seeing any issues.
