Comment (by bambambam):

 I use WordPress 4.9.6 and encounter similar symptoms:
 media empty, customizr blank, widgets not editable...

 javascript console:

 SyntaxError: illegal character
 mediaelement-and-player.min.js:12:87110
 ReferenceError: mejs is not defined
 mediaelement-migrate.min.js:1:16
 TypeError: b(...).not(...).filter(...).mediaelementplayer is not a
 function[Weitere Informationen]
 load-scripts.php:99:634
 TypeError: e is undefined
 load-scripts.php:354:1538

 no polylang or other language plugins are used.
 life site, so i did not disable all plugins.
 test site runs same WP version, same plugins, no error, ui working fine.
 did you find out anything about the media player error?

 thank you in advance!
 Martina
