I have a pane on my front page with one content pane and two views panes.

I can't see the content of the third view ($pane->pid = "new-3" / comment: # Senaste bilder).

Here's my panel

I have edited one views template, here's the code in the file views-view-fields--senaste-bilderna.tpl.php

<?php
// $Id: views-view-fields.tpl.php,v 1.6 2008/09/24 22:48:21 merlinofchaos Exp $
/**
 * @file views-view-fields.tpl.php
 * Default simple view template to all the fields as a row.
 *
 * - $view: The view in use.
 * - $fields: an array of $field objects. Each one contains:
 *   - $field->content: The output of the field.
 *   - $field->raw: The raw data for the field, if it exists. This is NOT output safe.
 *   - $field->class: The safe class id to use.
 *   - $field->handler: The Views field handler object controlling this field. Do not use
 *     var_export to dump this object, as it can't handle the recursion.
 *   - $field->inline: Whether or not the field should be inline.
 *   - $field->inline_html: either div or span based on the above flag.
 *   - $field->separator: an optional separator that may appear before a field.
 * - $row: The raw result object from the query, with all data it fetched.
 *
 * @ingroup views_templates
 */
?>
<?php foreach ($fields as $id => $field): ?>
    <?php $result = db_query('SELECT * FROM {files} WHERE fid = ' . $row->node_data_field_picture_field_picture_fid ); ?>
    <?php $data = db_fetch_object( $result );   ?>
    <div id="senaste-bilderna-first"><img src="<?= imagecache_create_url('senaste_bilderna_thumbnail', $data->filepath) ?>" alt="" /></div>
  <?php /* if (!empty($field->separator)):
    <?php print $field->separator;
  <?php endif; 

  <<?php print $field->inline_html; class="views-field-<?php print $field->class; ">
    <?php if ($field->label): 
      <label class="views-label-<?php print $field->class; ">
        <?php print $field->label; :
      </label>
    <?php endif; 
      <?php
      // $field->element_type is either SPAN or DIV depending upon whether or not
      // the field is a 'block' element type or 'inline' element type.

      <<?php print $field->element_type;  class="field-content"><?php print $field->content; </<?php print $field->element_type; >
  </<?php print $field->inline_html;>
<?php*/ endforeach; ?>

This is the result

<div class="panel-separator">
</div>
<div class="panel-pane pane-views-panes pane-senaste-bilderna-panel-pane-1" id="pane-senaste-bilderna"> 
  <h2 class="pane-title">Senaste bilderna från galleriet
  </h2> 
  <div class="pane-content"> 
    <div class="view view-senaste-bilderna view-id-senaste_bilderna view-display-id-panel_pane_1 view-dom-id-2">

        </div> 
      </div> 
    </div>   
  </div>
</div>
