I have applied this patch to the Views module so that it will add the channel properties of pubDate and lastBuildDate.
Then I ran Drupal "Clear all caches" within /admin/config/development/performance.
The added channel properties are only available for the first page requested each time after running another Drupal "Clear all caches".
For Drupal 7 how can I ensure that views RSS channel properties that are added with hook_views_query_alter() remain?
I have already tried the “Views RSS” module and after downloading and enabling this module along with its associated “views_rss_core” the “RSS Feed – Fields” radio button does not display and only the “RSS Feed” option is present which comes from the “Views” module.
