为什么我的WordPress可视化编辑器不起作用？

Question

I have website running WordPress 4.6.2 and I can't use the visual editor right now, only the text editor. When I open the browser console it show various errors.

I've been working on this problem for a good few hours and tried:

• restoring WordPress
• deactivating plugins
• deactivate the custom CSS used in the site
• Looking for can_compress_scripts in the DB and all various stuff that I stumble upon internet but with no success whatsoever
• Used theme is Spacious
• Include define('CONCATENATE_SCRIPTS', false); into wp-config.php
• Replaced TinyMCE folder content with TinyMCE content from clear installation
• A screenshot of the error from my web browser's console (below):

Answer 1

Apparently deleting few plugins solved the problem. The weird thing is that the problematic plugins were YoastSEO and Akismet and even after their reinstall i got tons of errors too.
