I just purchased MD Make and installed. I am getting the same two errors as another user (See Copied Post Below). My questions:

1. You gave the fix for the first error. Is the code that was posted (as shown below correct)?

2. What is the fix for the second error - Invalid argument supplied foreach()?

Text Copied from previous post:

Hi

this is it???

 // Content Tab
  $tabcontent_data = theme_get_setting('tabcontent_data');
  if (!empty($tabcontent_data)){
    $tabcontent_data = drupal_json_decode($tabcontent_data);
    $tabcontent_data = array_chunk($tabcontent_data, 3);
  }
  $menu_content = '<nav class="main-nav"><ul>';
  $tab_content = '';
  foreach ($tabcontent_data as $key_content => $content_detail) {
    if ($content_detail[0]['value'] != '') {
      $list_active = ($key_content == 0) ? "active" : "";
      $menu_content .= '<li><a href="#tab_cotent_' . $key_content . '" class="' . $list_active . '">' . t($content_detail[0]['value']) . '</a></li>';

      $section_show = ($key_content == 0) ? "show" : "hide";
      $tab_content .='<section class="content ' . $section_show . '">                    <h1>' . t($content_detail[0]['value']) . '</h1>
                    <h5>' . t($content_detail[1]['value']) . '</h5>
                    <div class="maintenance_description">' . t($content_detail[2]['value']) . '</div>
            </section>';
    }
  }

because i still have one error

Warning: Invalid argument supplied for foreach() in md_make_preprocess_maintenance_page() (line 491 of /home/artpt/public_html/beta2/sites/all/themes/md_make/theme_setting/front/page.preprocess.inc).
