title: Redactor wysiwyg image upload not working and no errors
body: <p>I'm trying to implement redactor wysiwyg and I have problems with image upload.</p>
  
  <p>Controller</p>
  
  <pre><code>public function upload()
  {
      $config = array(
          'upload_path' =&gt; './uploads',
          'allowed_types' =&gt; 'gif|jpg|jpeg|png|bmp',
          'max_size' =&gt; '60000',
          'encrypt_name' =&gt; TRUE,
          'remove_spaces' =&gt; TRUE
      );
      // load upload library and initialize config file
      $this-&gt;load-&gt;library('upload', $config);
  
      if($this-&gt;upload-&gt;do_upload('file'))
      {           
          $image_data = $this-&gt;upload-&gt;data();
  
          $json = array(
              'filelink' =&gt; base_url("uploads/{$image_data['file_name']}")
          );
          echo stripslashes(json_encode($json));
      }   
  }
  </code></pre>
  
  <p>View</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  $(document).ready(
      function()
      {
          $('#redactor').redactor({ 
              imageUpload: "http://localhost/rms2/admin/pages/upload",  
              minHeight: 150
          });
      }
  );
  
  &lt;/script&gt;
  
  &lt;?php echo form_open_multipart($this-&gt;uri-&gt;uri_string())?&gt;
     &lt;div class="form"&gt;
       &lt;div class="horizontal"&gt;
         &lt;div class="label"&gt;&lt;?php echo form_label('Description', 'description')?&gt;&lt;/div&gt;
         &lt;div class="input"&gt;&lt;?php echo form_textarea('description', set_value('description'), 'id="redactor"')?&gt;&lt;/div&gt;
         &lt;div class="form_error"&gt;&lt;?php echo form_error('description')?&gt;&lt;/div&gt;
  &lt;/div&gt;

  <p>The main problem is that I don't get any errors when I try to upload a image and if I drag it I get the message loading 100% like the image is uploaded, but no image, in the source file no  tag, nothing.</p>
  
  <p>Did anybody encounter this problem ??</p>
  
  <p><strong>EDIT</strong>:</p>
  
  <p>The link provided to image upload is not getting requested as I tried with a link outside CI(just a simple php file upload) and it works just fine, design pattern of the system is HMVC, anybody willing to give a hand or suggestions?</p>
