I personally emailed over 50 Nicasio Design clients on Feb 1, 2020 alerting them of the importance of keeping their WordPress websites & themes up to date as well as all subsequent plugins.

Since then we have had 7 clients contact us with critical errors preventing their sites from loading!

Preventive actions are less costly and pressing than actions due to adverse situations like a website completely inaccessible due to PHP and theme and  plugins compatibility issues.
