    I am using a 2nd database in the same MySQL server running the latest WP 5.4, latest MYSQL, and latest W3 Cache on Ubuntu 18. I am saving to this database logs which I want to keep separate from my primary WordPress installation. I am using the WP syntax to access another database. However, when using 2nd database with activated caching, I get this:

    Attempt to create object of class W3TC\Exception has been made, but file /var/www/myroot/htdocs/wp-content/plugins/w3-total-cache/Exception.php doesnt exists#0 w3tc_class_autoload(W3TC\Exception) #1 spl_autoload_call(W3TC\Exception) called at [/var/www/myroot/htdocs/wp-content/plugins/w3-total-cache/DbCache_WpdbNew.php:25] #2 W3TC\DbCache_WpdbNew->__construct(admin, ‘PASSWORD’, logging, localhost) called at [/var/www/myroot/htdocs/wp-content/themes/polly/inc/theme-settings.php:146] #3 require_once(/var/www/myroot/htdocs/wp-content/themes/polly/inc/theme-settings.php) called at [/var/www/myroot/htdocs/wp-content/themes/polly/functions.php:37] #4 include(/var/www/myroot/htdocs/wp-content/themes/polly/functions.php) called at [/var/www/myroot/htdocs/wp-settings.php:497] #5 require_once(/var/www/myroot/htdocs/wp-settings.php) called at [/var/www/myroot/htdocs/wp-config.php:135] #6 require_once(/var/www/myroot/htdocs/wp-config.php) called at [/var/www/myroot/htdocs/wp-load.php:37] #7 require_once(/var/www/myroot/htdocs/wp-load.php) called at [/var/www/myroot/htdocs/wp-blog-header.php:13] #8 require(/var/www/myroot/htdocs/wp-blog-header.php) called at [/var/www/myroot/htdocs/index.php:17]

    Looks like a problem which has not been predicted by developers…?
