Various Notice: Undefined index: at admin/reports/views-plugins

I ran into the same issue with views_data_export. Search the site database for web_widgets and reference_field. You will probably find remnant system records that gets found by views. I deleted those entries, and didn't get any new errors.

Of course test this on a development environment before trying it on your live site!

Any suggestion as to which database tables to search?

Hi guys...
I use the version 7.34 and under admin/reports/Views plugins i see this msg:
Notice: Undefined index: module in views_plugin_list() (line 278 of /home/mswebit/domains/msweb.it/public_html/calabria/sites/all/modules/views/views.module).

My website work well but i don't know why i see this msg!!!
Any ideas how to eliminate this error msg?
thanks

I just saw this problem with a migration I did from D6 to D7.

I had a content type that I wasn't using, so I deleted it, but did not delete the views that used it first. There were all sorts of remnants from the old content type in the database.

If you look at the report under admin/reports/views-plugins, I saw several fields that had some blank fields next to them, all of which were related to the deleted content type.

I ended up going through each table and physically removing every data entry associated with the deleted content type, and deleting the tables that held the remnant fields. Fortunately, this was not a large site.

I removed them from my localhost, then exported the entire DB to my dev db and on up the foodchain.

Hi guys, how are you?

I check it using the last stable version, and I check this function:

<?php
function views_plugin_list() {
  $plugin_data = views_fetch_plugin_data();
  $plugins = array();
  foreach (views_get_enabled_views() as $view) {
    foreach ($view->display as $display_id => $display) {
      foreach ($plugin_data as $type => $info) {
        if ($type == 'display' && isset($display->display_plugin)) {
          $name = $display->display_plugin;
        }
        elseif (isset($display->display_options["{$type}_plugin"])) {
          $name = $display->display_options["{$type}_plugin"];
        }
        elseif (isset($display->display_options[$type]['type'])) {
          $name = $display->display_options[$type]['type'];
        }
        else {
          continue;
        }

        // Key first by the plugin type, then the name.
        $key = $type . ':' . $name;
        // Add info for this plugin.
        if (!isset($plugins[$key])) {
          $plugins[$key] = array(
            'type' => $type,
            'title' => check_plain($info[$name]['title']),
            'module' => check_plain($info[$name]['module']),
            'views' => array(),
          );
        }

        // Add this view to the list for this plugin.
        $plugins[$key]['views'][$view->name] = $view->name;
      }
    }
  }
  return $plugins;
}
?>

And it's okay now. Please update for make a test. Now it's all right using the last version of Drupal Core (7).

Best,
