1. In the background of WordPress, when switching from the code to visualization, it cannot be switched, and the console reports an error: uncaught typeError: _.pluck is not a function. as shown in Figure 1
2. The description code uses _.pluck(), but the currently loaded version of the underscore.js has been removed. However, some old plugins, themes, or core JS files of WordPress still call _.pluck(), resulting in an error.
3. In the end, I had to disable the classic editor and enable Gutenberg. as shown in Figure 2
