No theme no highlight

Hi Codemirror is installed as a tinymce 4 plugin Codemirror seems to work correctly, I can edit source code, managed options like windows size but as you can see on screen shot there is no highlight and themes are not shown : 2020-03-11_23h37_06 Here is config init.js :

codemirror: { indentOnInit: true, // Whether or not to indent code on init. fullscreen: false, // Default setting is false path: 'codemirror-4.8', // Path to CodeMirror distribution saveCursorPosition: true, // Insert caret marker config: { // CodeMirror config object mode: 'application/x-httpd-php', lineNumbers: true }, cssFiles: [ 'theme/neat.css', 'theme/elegant.css' ], width: 600, // Default value is 800 height: 500 // Default value is 550 },

Mode folders and themes files are presents :
