 Replying to [comment:3 johnxba]:
 > "Uncaught EvalError: call to Function() blocked by CSP" is Firefox
 complaining (F12) about the use of eval in scripts. Eval must not be used
 in scripts because it is a security risk. CSP (Content Security Policy)
 can be used to enforce protection.

 > Why eval should not be used in Javascript:
 > The error appears when wp-admin is used and an admin is logged in. In
 the current version of WordPress, two of the scripts containing eval
 according to Firefox are:
 > wp-includes/js/wp-util.min.js?ver=5.8:2
 > wp-includes/js/underscore.min.js?ver=1.8.3:2
 > Please remove the use of eval in scripts in WordPress.
