Thanks, setting “define(‘WP_DEBUG’, false);’ did hide the Notices.
BTW, for completeness, before changing ‘WP_DEBUG’ I did clear the cache in Google Analytics -> General Settings, but it did not help.
Also, the notices did not show up when viewing ‘Yesterday’ and ‘Today’ stats but did show up for all the “Last x Days” filters.
My graphs and stats are properly displayed.
I changed the error_reporting setting in php.ini to this:
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE
and restarted Apache but the Notices still show.
