Getting errors on chart display after upgrading to 1.40 LTS:
Call to undefined method Wikimedia\Rdbms\DatabaseMysqli::fetchRow()
Looks like this is known, fetchRow deprecated:
Release notes/1.39#Breaking changes in 1.39
The raw Individual Hit values still show, but chart display and any of the other lists fail on fetchRow().
I've used this extension for several years to get details and have quick traffic charts, so sad to see this finally dying. (Yes, I know it is unmaintained.)
