Since upgrading to WP 4.6, I’m seeing a nightly error in my logs on one of my sites using relevanssi:
[08-Sep-2016 05:00:29 UTC] PHP Fatal error: Call to undefined function is_plugin_active() in /home/XX/public_html/wp-content/plugins/relevanssi/lib/indexing.php on line 733
Auto-indexing appears to be failing.
Anybody else seeing this?
