The error of "Warning: “continue” targeting switch is equivalent to “break”. Did you mean to use “continue 2"?" caused by your CMS did not support newer PHP version. There 2 solutions:
- Repair your code to support PHP >= 7.3 version
- Downgrade to PHP 7.2
Of course, revise your code to support newer PHP version is the best way, but sometimes you have no choice rather than downgrade your PHP version to 7.2.
