I did not change anything on this file...
It's not a visual problem but a compiler error. So that several functions i.e. "Insert image" don't work.

But here is the file Themes/Custom/style.css.aspx:

 

 

<%@ Page Language="C#" ContentType="text/css" %>
<%@ OutputCache Duration="31536000" VaryByParam="None" Location="Client" %>

<script runat="server">
   string editorid;
   protected override void OnInit(EventArgs e)
   {
   //do not call base's OnInit , skip the theme bug!
      //base.OnInit(e);
   editorid="#"+Request.QueryString["EditorID"];
   }
</script>
