Dear fede312,
I updated the file: /plugins/system/ytshortcodes/ytshortcodes.php
The code that I changed is:
if($editor == "jce" || $editor == "none")
{
$page = str_replace('<div id="editor-xtd-buttons" class="btn-toolbar pull-left" role="toolbar" aria-label="Toolbar">','<div id="editor-xtd-buttons" class="btn-toolbar pull-left" role="toolbar" aria-label="Toolbar">'. $button.'</div><div class="toggle-editor btn-toolbar pull-right clearfix">', $page);
}
after the code: $editor = $app->getCfg('editor');
Thanks
