You hit the WordPress update button forgetting that WordPress W3TC Plugin has not been disabled. Update screen may get stuck with no information. From another window, you tried to navigate towards any webpage of your website where WordPress Admin privilege is needed, you will get “Database Update Required” message. This Database Update Required is an infamous message in most cases. When you’ll try to hit the button of Database Update Required Message Window, PHP-FPM will fail.

define('WP_CACHE', true); // Added by W3 Total Cache
...
define('W3TC_EDGE_MODE', true); // Added by W3 Total Cache

like this :

Vim
1
2
3
4
...
// define('WP_CACHE', true); // Added by W3 Total Cache
...
// define('W3TC_EDGE_MODE', true); // Added by W3 Total Cache

Use ^ + W in nano to find the lines. save the file. Now, go to wp-content/plugins directory and rename the plugin directory :

/usr/share/nginx/html/wp-content/plugins
Vim
1
mv w3-total-cache w3-total-cache-disabled

/usr/share/nginx/html/wp-content/
Vim
