Hi @vmarko
I recently received a email from Developers regarding one more error:

TypeError: mysqli_num_fields(): Argument #1 ($result) must be of type mysqli_result, bool given File "/wp-content/plugins/w3-total-cache/DbCache_WpdbInjection_QueryCaching.php", line 218, in W3TC\DbCache_WpdbInjection_QueryCaching::query 'col_info' => $this->wpdb_mixin->col_info, File "/wp-content/plugins/w3-total-cache/DbCache_WpdbNew.php", line 122, in W3TC\DbCache_WpdbNew::query return $this->active_processor->query( $query ); File "/wp-content/plugins/wordpress-seo/lib/orm.php", line 287, in Yoast\WP\Lib\ORM::execute $result = $wpdb->query( $query ); File "/wp-content/plugins/wordpress-seo/lib/orm.php", line 1954, in Yoast\WP\Lib\ORM::run $success = self::execute( $query, $this->values ); File "/wp-content/plugins/wordpress-seo/lib/orm.php", line 385, in Yoast\WP\Lib\ORM::find_one $rows = $this->run(); ... (14 additional frame(s) were not displayed)

P.S: We have received this from Sentry .

Hi @vmarko
Thank you so much for the Prompt reply.

I just got the chance to read the wiki you shared above, I think we need to enable that DB option in wp-config file. As I explained during my question we will have multiple servers and Since there is Scaling, Instances will keep on scaling up and down as required.

And, yes we are using DB caching with AWS Managed Redis (Elastic Cache).

Just for your information our site is : https://www.homeloanexperts.com.au/

Please feel free to suggest a better setup how you feel is good for this website.

Thank you,
