I am using mruby in my project <And when I delete mruby files, don't miss

And my second problem: I am using a tag script

in my page and not working

<script src="http://cdnjs.cloudflare.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script src="http://d1n0x3qji82z53.cloudfront.net/src-min-noconflict/ace.js" type="text/javascript" charset="utf-8"></script>

      

        
        
        
      

    

I don't have this problem on localhost, but only when I click

Can anyone help me?
