Ckeditor is not showing my code block when I edit it. I show it with the screenshots below.
myconfig file:
config.toolbar = 'Full';
config.extraPlugins = 'sourcedialog';
config.extraPlugins = 'codemirror';
config.fillEmptyBlocks = false;
config.autoParagraph = false;
config.allowedContent = true;
config.extraAllowedContent = 'pre[*]; code[*]';
config.extraPlugins = 'codesnippet';
