    Thanks for the reply. I run and moderate a couple of websites and fully appreciate your comments. While not chartered I too am an Engineer and know what PHP is but little more.
    To reiterate, upgrading to WP 4.9 broke (or at least severely impaired) one of the websites I look after. (I have not updated any of the other websites to WP 4.9.) In search of help, I ended up in this thread where you appear to have experienced the same problem, i.e. the warning with the reference to line 1657 in wp-db.php.
    I (like you) have now downgraded back to WP 4.8.3 on the site I had upgraded to WP 4.9. The website is now working fine again.
